AU - Detweiler, Susan. AU - Fitzpatrick, Richard E.. PY - 2008/2. Y1 - 2008/2. N2 - Background/Objective: Various techniques for blepharoplasty have been described, including those performed with the assistance of the short pulse carbon dioxide laser and those performed with the assistance of the Colorado microdissection needle attached to an electrocautery unit. Although the superiority of the carbon dioxide laser to cold steel has been demonstrated for the performance of eyelid blepharoplasty, no studies have ever compared the carbon dioxide laser to the Colorado needle. Study Design/Materials and Methods: This is a paired comparison study in which 12 healthy patients underwent bilateral blepharoplasty of their upper and/or lower eyelids by a single surgeon. For each patient, a short pulse carbon ...
Five individuals who meet the eligibility criteria will take part in this study. They will have a variety of assessments performed throughout the treatment period in order to evaluate both dermatomyositis and calcinosis severity and their potential response to fractional carbon dioxide and sodium thiosulfate treatment. A medical history will be taken and baseline assessments will be performed during the screening period. Serum creatinine kinase levels will be determined on this visit and repeated at the end of the study (week 20); these levels will be one measure of monitoring disease activity during the study. One calcinosis lesion will be treated, assessed, and followed. If a second calcinosis lesion is present, it will act as a control (not treated). Two weeks prior to the first treatment session, an optional (not required) skin biopsy of the target (treated) calcinosis lesion will be offered to the the first 3 patients ≥ 18 years of age to determine optimal fractional carbon dioxide laser ...

For high power CO2 lasers the discharge tube consists of a number of tubes placed in a parallel configuration with ar-rangement for optical folding of light through back and forth reflections. The slow axial flow lasers can produce a maximum output of about 500 watts be-cause 75 - 90% of the discharge energy is dissipated in the gas resulting in its overheating and decomposition with consequential fall in output. For higher output the gas is driven through the laser tube at a high speed by a blower; this reduces the heat loss to the walls to a negligible amount. While a slow axial flow laser will deliver about 50 - 70 watts per meter of laser cavity, the fast axial flow laser can generate upto 600 watts per meter. Gas Laser Operation: In a carbon dioxide laser the CO2 molecules are vibrationally excited by an electric discharge across the laser cavity. The direct vibrational excitation of CO2 by an electric discharge is inefficient. However, N2 accepts energy effectively from the discharge and ...

There has been a lot of talk about the fractional CO2 laser this year. Dermatologists are very excited about this recently launched laser and the anti-aging effect it produces. Fractional Carbon Dioxide Laser works by creating millions of microscopic wounds that cause the skin to go into a repair mode and increase collagen production. As a result skin is firmed, fine lines and wrinkles are reduced, skin tone is evened out. Another thing dermatologists are so happy about is that the time needed for a recovery is not as long as compared to other similar laser treatments. According to Elle (US, August 08) one needs a week for a full recovery, while some may experience "slight redness" for up to a month. However in another Elle article in December issue three women undergoing this procedure give a feed back on their recovery which seems a bit longer than just a week. Their skin looks burnt till it peels off only around 14-15 days after treatment and a month later they describe their skin being ...
Pre-Treatment:. Timing of laser best between September 15th and April 15th to avoid Summer sun.. 4 to 6 weeks prior to treatment- If Fitzpatrick skin classification IV or V (VI is not treated by CO2 laser)- test patches are performed at four different energy settings (two behind each ear). One-week prior- Cleansing facial with extractions and either or a combination of chemical peels (usually mandelic and salicyclic), dermal planning, and/or microdermabrasion (in that order if multiple aesthetician treatments).

Though you always find an individual who has a lower threshold for pain, most of my patients find laser treatment very tolerable. In their opinion, its not painful at all. Therefore, the procedure is usually performed with local anesthetic creams or even without anesthesia. The treatment session takes about 45 to 90 minutes with 3 to 7 days interval between sessions.. By targeting water as its chromophore, the laser induces a dense array of microscopic, columnar thermal zones of tissue injury that do not perforate or impair the function of the outer layer of the skin (epidermis). The treated skin area rapidly recovers with newer skin and healthy tissue (Non-Ablative Therapy).. The fractionated carbon dioxide laser beam is broken into numerous microscopically thin beams that strike the skin and vaporize sun damaged or scarred tissue. This causes the skin to tighten, and during healing, produce collagen - the protein responsible for skin structure and appearance (Ablative Therapy).. When therapy ...
Coherent introduces a new generation of carbon monoxide (CO) lasers for materials processing, built on the framework of Coherents well established slab/waveguide CO2 technologies. The characteristic 5.5µm emission wavelength offers advantages and alternatives to traditional 10.6µm CO2 lasers. The smaller wavelength and M2 ,1.2 leads to smaller spot sizes at a focus for higher spatial processing resolution creating higher power densities. For materials with greater transparency at 5.5µm the increased depth of penetration leads to cleaner scribes and cuts and smaller heat affected zones. For materials with stronger absorption, higher throughput at lower average powers can be realised.. Currently available in the J-3 series platform (,200W) the Coherents CO laser benefits from key design features of the J-3 CO2 of carbon dioxide lasers, including a long lifetime and completely sealed head..

They are often used as an alternative or and adjunct to the drill.. In many cases, tooth preparation with a laser does not require anaesthetic (injections). For larger fillings we sometimes recommend anaesthetic still.. The strength of the laser can be adjusted, which will alter the sensation and sound you hear. Because we can alter the strength, we can chose to make the laser strong enough to cut only decay, and not surrounding healthy tooth.. The size of the laser beam is much smaller than a standard drill, which makes it an excellent conservative option. Sometimes the procedures take a little longer because of this.. Using a laser can improve how well a filling bonds to the tooth surface.. The area it cuts creates a completely sterile environment, which is particularly useful when removing decay. Also, where the gum needs re-shaping, this means that the area is much cleaner, and will heal faster, with less discomfort.. If there is a localized area of infection, a laser can be used to ...

The University of Florida Whitney Laboratory Sea Turtle Hospital is now using advanced carbon dioxide laser technology in the treatment of its sea turtle patients that are infected with the Fibropapilloma virus (FP). The FP virus creates internal and external tumors on the sea turtle that inhibit normal functioning such as mobility, eating and vision. While the cause of the virus is unclear, the current form of treatment is the removal of the external growths once the sea turtle is healthy enough to undergo surgery. Now at the Sea Turtle Hospital, a carbon dioxide laser is used during surgery to remove the tumors, thanks to a generous donation from a sea turtle enthusiast and community member. Since there are very few grants available to sustain programs such as these, donations to the hospital are incredibly important.. The first surgery at Whitney Laboratory using the laser treatment took place on April 11, 2016. Cisco Kid, a juvenile green sea turtle found stranded on Hammock Beach in Palm ...

Ablation of cataractous human eye lens tissue with carbon dioxiqe laser beam of wave-length 10.6 μm is investigated at power densities upto 20 KW/cm2 with interaction time in the rnge of 4-20 msec. It is found that the ablation initiates at a fluence of about 26 J/cm2 and thereafter the ablated volume of the tissue increases with the laser fluence with a decreasing slope. A well defined zone of coagulation necrosis borders the laser ablated region and its width increases with the power density and interaction time of the laser beam. From the thermal behaviour of the cataractous lens tissue, it is found that at the onset of ablation, tissue attains a temperature of about 270°C. To confine this temperature to a reasonably small volume, short duration laser pulses will be ideal for ablating the cataractous lens ...

A method for manufacturing a glass core rod and a cladding layer clothing the glass core rod applied successively or continuously by using a carbon dioxide gas laser. A refractory mandrel is heated by means of carbon dioxide gas laser irradiation and a mixed gas of oxygen and pure silicon tetrachloride vapor and a dopant compound vapor is ejected to the refractory mandrel so as to deposit silicon oxide and oxide of the dopant compound on the mandrel and to form a glass core by fusing it. Further heating is applied by irradiation by the carbon dioxide laser beam on the glass core and a mixed gas oxygen and pure silicon tetrachloride vapor and a dopant compound vapor or of oxygen gas and pure silicon tetrachloride vapor to deposit silicon oxide and oxide of the dopant compound or silicon oxide on the glass core to form a cladding layer of fused silica or fused silica containing the dopant. The preform thus formed by the glass core and the cladding is heated above the softening temperature of the preform
Gemstones are typically thought of as no more than decorative stones used in jewelry and other luxury items, but did you know that these brilliantly colored crystals and gems are used in everything from watches and radios to industrial drills and lasers?. Lasers were first used in medical procedures more than four decades ago for vascular vein conditions using gases, like argon, bromium or carbon dioxide, as a medium through which the laser passed. A major side effect of using gas laser treatments with long pulse durations was too much scarring.. Although gases are still used to conduct the laser light, the technology has been revolutionized with the carbon dioxide laser that now has more accurate pulse durations to limit unwanted thermal damage and by switching out gases for gemstones. In fact, some of todays most effective laser treatments are powered by gemstones because of their precision and versatility, making laser technology effective in a much broader range of industries, including ...

A dental laser is a type of laser designed specifically for use in oral surgery or dentistry. In the United States, the use of lasers on the gums was first approved by the Food and Drug Administration in the early 1990s, and use on hard tissue like teeth or the bone of the mandible gained approval in 1996. Several variants of dental lasers are in use with different wavelengths and these mean they are better suited for different applications. Diode lasers Carbon dioxide lasers Nd:YAG laser Diode lasers wavelengths in the 810-1,100 nm range are poorly absorbed by the soft tissues such as the gingivae, and cannot be used for soft tissue cutting or ablation. Instead, the distal end of diodes glass fiber is charred (by burned ink or by burned corkwood, etc.) and the char is heated by the 810-1,100 nm laser beam, which in turn heats up the glass fiber tip. The soft tissue is cut, on contact, by the hot charred glass tip and not by the laser beam. Similarly ND:YAG lasers are used for soft tissue ...

How are laser procedures performed?. Different types of dental laser have been created to treat different conditions. Each laser uses a different wavelength of light, which predicates its best use. The most common types of dental laser are carbon dioxide lasers and diode lasers, which are usually employed to treat soft tissue problems. The dentist will decide which type of laser is best to use after conducting X-rays and a thorough examination.. The laser beam is extremely bright, and special glasses will be provided to protect the eyes. The dentist will then direct the beam at the affected area and carefully dissolve the soft tissue, harden the filling or whiten the teeth.. The procedure will take far less time than conventional methods, and cause far less anxiety and discomfort. The only real disadvantage of laser dentistry is that it can prove to be more expensive.. If you have questions or concerns about laser dentistry, please ask your dentist.. ...

Treatment is determined on the basis of the number, size, and location of the oral KS lesions. The choice of therapy depends on the effect of treatment on the adjacent mucosa, pain associated with treatment, interference with eating and speaking, and the patients preference. It is important to perform thorough dental prophylaxis before initiating therapy for KS lesions involving the gingiva. Response to therapy is improved if all local plaque and calculus are removed. Local application of sclerosing agents may reduce the size of oral lesions.(72) Local treatment is appropriate for large oral KS lesions that interfere with eating and talking.(72,73) Oral KS can be treated surgically or with localized intralesional chemotherapy. Surgical removal is suitable for small, well-circumscribed lesions such as gingival or tongue lesions.

A multi-wavelength laser array where each element can be individually heated for fine tuning. The wavelength of the array can be coarsely tuned by selecting one laser of a particular wavelength for the array, and then applying a heating current to fine-tune the wavelength. The lasers can be phase shifted DFBs for high single-mode yield. The heating can be performed monolithic to the device by passing current longitudinally through the p-type stripe, while the injection current passes vertically through the stripe. Alternatively an adjacent laser to the one selected can be activated, though not fiber coupled, such that the thermal load is sufficient to tune the selected laser. Thin film heaters placed on top or adjacent to the cavity can also be used. To minimize continuous power consumption, the on-chip heater can be used initially to tune the laser while the TE cooler responds on a slower time scale.
