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 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 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.
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 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.
Is argon laser a four level laser?
Working of Argon Ion Laser 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.
Which laser is used in CD player?
A Blu-Ray player uses blue laser light to probe the bumps and pits of the disc and a CD player uses red laser light. The relatively short-wavelength blue light is necessary to probe the smaller pits and bumps on a Blu-ray disc; smaller pits and bumps correspond to higher storage densities.
How do c02 lasers work?
Ablative lasers, such as a CO2 laser, work by traumatizing the skin. It removes the thin outer layer of skin (epidermis) and heats the underlying skin (dermis). This stimulates the growth of new collagen fibers. As the epidermis heals and regrows, the treated skin appears clearer, smoother and tighter.
Why is krypton used in laser eye surgery?
Possible advantages of krypton laser therapy for choroidal neovascularization (CNV) include its ability to penetrate foveal xanthophyll and retinal blood vessels and to minimize damage to the nerve fiber layer. Krypton also penetrates the xanthochrome in nuclear sclerotic cataract.
What is PRP in ophthalmology?
Panretinal photocoagulation (PRP) is an extensive laser treatment applied to the peripheral retina inside of your eye. This treatment is recommended when abnormal blood vessels are growing inside of your eye.
Where is ND YAG most commonly used?
Where is ND: YAG most commonly used? Explanation: ND: YAG is most commonly used for cosmetic energy because it has the property of maximum energy absorption by the target (hair or lesion) with minimum absorption by the surrounding skin structures. Explanation: Laser has a large bandwidth.
What is the YAG procedure?
The procedure helps to permanently improve vision by replacing the natural lens of the eye with an artificial lens that requires no upkeep or care as glasses do. A YAG laser procedure is a common necessity for patients that have undergone cataract surgery in order to tweak results for an optimal outcome.
How does a ruby laser work?
A ruby laser most often consists of a ruby rod that must be pumped with very high energy, usually from a flashtube, to achieve a population inversion. The rod is often placed between two mirrors, forming an optical cavity, which oscillate the light produced by the ruby’s fluorescence, causing stimulated emission.
