275 to 686 nm
6.2 Argon Ion and Krypton Ion Laser. The argon ion laser and the krypton ion laser provide a wide range of visible and ultraviolet laser wavelengths. They produce CW output at wavelengths ranging from 275 to 686 nm and powers of up to tens of watts.
How does argon ion laser work?
The Argon ion Laser is a four-level laser. The various energy level of argon ion is shown in the figure. When electric discharge passes through the tube, the Argon atoms are pumped to energy level E3 by two-step of collision with electrons.
Why is argon used in lasers?
Many dermatologists have used argon lasers to treat ulcers, lesions and polyps. Other medical applications include photocoagulation and many ophthalmologic procedures. The advantage of using an argon laser for these applications is due to the fact that it has the ability to target a precise area.
What type of laser is the argon ion laser?
Argon ion lasers are ion lasers, which typically generate multiple watts of optical power in a green or blue output beam with high beam quality. They are the most common ion lasers, and can produce the highest output powers of those.
What is the frequency of argon?
Experiments confirmed that standing striations exist in Argon CCP at frequencies 3.6, 8.4 and 19.0 MHz, in a pressure range 0.05-10 Torr, for a certain range of discharge currents (plasma densities).
What type of ion is argon?
Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv)….Argon.

What type of ion is Argon?
Who drops the ion laser?
EVIL Saint Lawrence
The ION Laser can be obtained from any loot source but has a high chance of dropping from EVIL Saint Lawrence who is located in The Spendopticon on the Handsome Jackpot.
What is argon gas laser?
The Argon laser is a laser system that uses noble gas as the active medium. Argon gas lasers are used in many applications such as forensic medicine, entertainment, general surgery, ophthalmic surgery, holography and as an optical “pumping” source.
What gases are used in lasers?
Gas Lasers are lasers that use an electric current discharged through a gas medium to produce a beam. Common Gas Lasers include helium neon, argon, or carbon dioxide. The type of gas used can determine or influence the laser’s wavelength, efficiency, or power.
What is argon welding?
The argon gas is widely used in different welding techniques. The argon welding gas serves as a shield for the fresh weld of its surrounding atmosphere. This provides several benefits, making the welds more seamless and durable.
What color is an argon laser?
blue/green
So how does an argon gas laser work? This device emits wavelengths of blue/green colored light that is a monochromatic light source and each wavelength has a very narrow bandwidth. In medical applications of the laser, the hemoglobin in the blood cells absorbs the blue/green colored light.
What are the characteristics of argon ion lasers?
Argon-ion lasers emit powerful lines at 488 and 514.5 nm, allowing initial excitation of fluorescein and rhodamine (and later emission of phycobiliproteins and their tandem dyes) (Shapiro, 2003). Argon-ion lasers also produce a relatively strong series of lines in the ultraviolet, particularly at 351 and 364 nm (Fig. 1).
What part of the electromagnetic spectrum does the Ar ion laser emit?
The Ar ion laser emission is in the blue-green part of the spectrum. This emission is well transmitted and well focused by the eye and may cause damage to the retina. When using the Ar laser, special goggles which block out the blue-green laser emission must be worn to protect the eyes.
What is the wavelength of a krypton-ion laser?
Krypton-ion lasers, more expensive and less common than argon, produce a wider variety of wavelengths, including UV lines at 351 and 356 nm, violet lines at 407 and 413 nm, a blue line at 476 nm, green and yellow lines at 520, 531 and 568 nm, respectively, and red lines at 647 and 676 nm ( Fig. 1) ( Shapiro, 2003 ).
What power supply do I need for an argon laser?
A 240 V three phase power supply and ca. 35 A are required for pumping a medium power 5 W argon ion laser. The tube also requires water cooling at a flow rate of ca. 10 L/min and a pressure of 25 psi because of the large amount of heat dissipation.
