The 871 Series Laser Wavelength Meter uses a proven Fizeau etalon-based design to measure the wavelength of both pulsed and CW lasers that operate from 375 nm to 2.5 μm. (photonicsonline.com)
Wavelength tuning speed and precision are key to acquiring high fidelity target data upon which advanced detection algorithms can operate. (sbir.gov)

The risk of damage to the skin is greater when there is little contrast between the color of the hair and skin, but advances in laser technology have made laser hair removal an option for people with darker skin. (gomecy.com)

However, the distinguishability on oil types is seldom considered while selecting excitation wavelength. (researchsquare.com)
It is also an innovation that this laser can be used on all skin types, so it holds promise to improve the texture of dark complexions without the risk of hyperpigmentation. (mentorplasticsurgery.com)
As a result, the Nd:YAG lasers are safe to use on darker skin types. (laserhairremovalathome.com)

At last, the 800 nm lasers provide optimal results on removing dark hair. (laserhairremovalathome.com)

There are two groups of laser that can remove unwanted hair: the red and infrared lasers. (laserhairremovalathome.com)
Laser hair removal is a medical procedure that uses a spotlight (laser) to remove unwanted hair. (gomecy.com)
Laser therapy is also used to remove unwanted hair, tattoos, skin discoloration, scars due to acne, or sun damage. (msdmanuals.com)
