• Under the appropriate conditions of electrical stimulation and high pressure, a pseudo-molecule called an excimer (or in the case of noble gas halides, exciplex) is created, which can only exist in an energized state and can give rise to laser light in the ultraviolet range. (wikipedia.org)
  • citation needed] The wavelength of an excimer laser depends on the molecules used, and is usually in the ultraviolet range of electromagnetic radiation: Excimer lasers, such as XeF and KrF, can also be made slightly tunable using a variety of prism and grating intracavity arrangements.

  • This laser used a high power thyratron and magnetic switching with corona pre-ionization and was rated for 100 million pulses without major maintenance. (wikipedia.org)
  • Procedural complications (abrupt closure 1.3%, side branch occlusion 1.9%, intimal dissection 6.3%, embolization 1.3%, filling defect 1.3%, perforation 1.9% and spasm 1.3% and major complications (non-Q wave myocardial infarction 4.8%, emergency coronary bypass surgery 3.5% and death 0%) were infrequent and predominantly related to subsequent balloon angioplasty.

  • However, when in an excited state (induced by electrical discharge or high-energy electron beams), they can form temporarily bound molecules with themselves (excimer) or with halogens (exciplex) such as fluorine and chlorine. (wikipedia.org)
  • While electron-beam pumped excimer lasers can produce high single energy pulses, they are generally separated by long time periods (many minutes). (wikipedia.org)
  • Most of the lasers produced were XeCl, and a sustained energy of 1 J per pulse at repetition rates of 300 pulses per second was the standard rating. (wikipedia.org)
  • Using a xenon chloride (308 nm) excimer laser generator and 1.5 to 1.75 mm catheters, excimer laser angioplasty was attempted at 135 ns pulse width, 25 to 40 Hz repetition rate, 2 to 5 s laser delivery time and 30 to 60 mJ/mm2 energy fluence. (nyu.edu)
