An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining.
With nine biweekly treatments, the 308-nm excimer laser showed a response rate of 60–70% for pigmentation stimulation in hypopigmented scars. To preserve the effects, though, a follow-up treatment is required every 1-4 months. [10]
Rangaswamy Srinivasan and James Wynne filed a patent application on the ultraviolet excimer laser, in 1986, issued in 1988. [32] In 1989, Gholam A. Peyman was granted a US patent for using an excimer laser to modify corneal curvature. [33] It was, "A method and apparatus for modifying the curvature of a live cornea via use of an excimer laser.
Meanwhile, experiments in 1970 using a xenon dimer and in 1975 using noble gas halides resulted in the invention of a type of laser called an excimer laser. While excimer lasers were initially used for industrial purposes, in 1980, Rangaswamy Srinivasan, a scientist of IBM who was using an excimer laser to make microscopic circuits in ...

Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
