Question: How does an argon laser work?

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.

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.

How does a gas laser work?

A gas laser is a laser in which an electric current is discharged through a gas to produce coherent light. The gas laser was the first continuous-light laser and the first laser to operate on the principle of converting electrical energy to a laser light output.

What does an 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.

Which gas is used in lasers?

The most common of all gas lasers is the helium-neon (He-Ne) laser. The presence of two atomic species (helium and neon) in this gas laser might suggest that the medium is made of molecules, but these two species of atoms do not form a stable molecule. In fact, all inert atoms like helium, argon, krypton, etc.

What is argon laser treatment?

The most common type of laser surgery performed for open-angle glaucoma is called Argon Laser Trabeculoplasty (ALT). The objective of the surgery is to help fluids drain out of the eye, reducing intra-ocular pressure that can cause damage to the optic nerve and loss of vision.

What is a gas laser used for?

Gas lasers have a wide range of uses. For example, carbon dioxide gas lasers have applications in industry, such as for cutting and welding. Helium-neon lasers are often used in physics labs and other educational settings and tend to be the least expensive.

Does a gas laser exist in nature?

These naturally-occurring lasers have puzzled astronomers for many years because they appear to occur in dilute gases made up of random atoms. Today, Robin Kaiser and pals at the Institut Non Linéaire de Nice in Southern France say they have created lasers that work in the same for the first time on Earth.

What are the advantages of gas laser?

The use of gaseous material in laser has certain advantages compared to other media like solid state and semiconductor. The volume of gaseous medium can be large, which makes it suitable for high-power lasers. There is no possibility of damage to the medium, which occurs in high-power ruby and glass lasers.

What color is argon laser?

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.

How much does an argon laser cost?

How Much Does Laser – Argon Cost? The prices of some systems can be as low as 500 USD or less, while the newest, high-tier systems may cost as much as 30.000 USD.

How does a Argon laser work?

How does Argon laser treatment work? During the treatment a laser beam is focused on the back of the eye. This beam of light is absorbed by the retina. This is used to seal leaking retinal blood vessels in diabetic retinopathy and retinal vein occlusions and to seal retinal tears.

How are argon lasers made?

The core component of an argon ion laser is an argon-filled tube, made e.g. of beryllium oxide ceramics, in which an intense electrical discharge between two hollow electrodes generates a plasma with a high density of argon (Ar+) ions.

What type of laser is KTP?

How KTP Laser Works. A KTP laser is a solid-state laser that uses a potassium titanyl phosphate (KTP) crystal as its frequency doubling device. The KTP crystal is engaged by a beam generated by a neodymium:yttrium aluminum garnet (Nd: YAG) laser.
