Subsequent work introduced the excimer laser for use in angioplasty. [36] Xenon chloride (308 nm) excimer lasers are also used to treat a variety of dermatological conditions including psoriasis, vitiligo, atopic dermatitis, alopecia areata and leukoderma. [citation needed] As light sources, excimer lasers are generally large in size, which is ...
A krypton fluoride laser (KrF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 248 nanometer wavelength, it is a deep ultraviolet laser which is commonly used in the production of semiconductor integrated circuits , industrial micromachining, and scientific research.
The argon fluoride laser (ArF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 193-nanometer wavelength, it is a deep ultraviolet laser, which is commonly used in the production of semiconductor integrated circuits, eye surgery, micromachining, and scientific research.
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).
There are many types and categories of tunable lasers. They exist in the gas, liquid, and solid states. Among the types of tunable lasers are excimer lasers, gas lasers (such as CO 2 and He-Ne lasers), dye lasers (liquid and solid state), transition-metal solid-state lasers, semiconductor crystal and diode lasers, and free-electron lasers.

Glow-in-the-dark coughs and sneezes? In the coronavirus era, this is what it takes for scientists to figure out which masks work best at stopping aerosol droplets from spreading after a cough or a ...
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.
A 2021 study found that the treadmill is the most effective cardio machine for weight loss. A trainer explains why—and reveals the best treadmill workouts.
