What do you mean by excimer laser?
Excimer is a term used today to describe a family of lasers with similar output characteristics, in that they all emit powerful pulses lasting nanoseconds or tens of nanoseconds, at wavelengths in or near the ultraviolet, and the lasing medium is a diatomic molecule, or dimer, in which the component atoms are bound in …
How is argon used in lasers?
The argon gas laser works by burning and sealing the blood vessels. The lasers give out continuous waves of milliwatts to tens of watts. It passes through tubes made of Nickel end bells, Kevlar metal to ceramic seals, beryllium oxide ceramics or tungsten disks.
Which one is the excimer gas laser?
6.6 Excimer Laser. Excimer lasers consist of mixtures of noble gas atoms such as argon, krypton, and xenon with reactive gases such as fluorine or chlorine operating in a special type of high-pressure gaseous discharge. They are therefore also known as rare gas-halide lasers.
Is argon a fluoride?
Argon fluoride (ArF) is currently the shortest wavelength laser that can credibly scale to the energy and power required for high gain inertial fusion.
How do excimer lasers work?
How do excimer lasers work? The excimer laser emits a cool beam of ultraviolet light of a specific wavelength (typically 193 nanometers) to precisely remove corneal tissue. An excimer laser corrects nearsightedness by flattening the cornea; it corrects farsightedness by making the cornea steeper.

What does the Argon laser look like?
The argon laser contains argon gas and produces a visible blue-green beam with wavelengths of 488 nm and 514 nm, which are absorbed selectively by hemoglobin, melanin, and other pigments that lie under the retina.
What kind of laser is Argon?
Argon laser The argon-ion laser was invented in 1964 by William Bridges at the Hughes Aircraft Company and it is one of the family of ion lasers that use a noble gas as the active medium. Argon-ion lasers are used for retinal phototherapy (for the treatment of diabetes), lithography, and the pumping of other lasers.
What is the wavelength of argon?
The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths.
What is argon used for?
Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.

How much does an excimer laser cost?
The big LASIK laser manufacturers in the United States charge well over $100,000 for an Excimer laser. The typical range is between $150,000 at the low end to nearly $300,000 at the high end.
