An argon laser has multiple uses in ophthalmology. It may be used for. Narrow-angle glaucoma treatment: An argon gas laser is used for trabeculoplasty for narrow-angle glaucoma. It improves the drainage of the aqueous humor (eye fluid). Repairing retinal tears and small retinal breaks: Small tears in the retina in individuals with high myopia or other diseases can be repaired with an argon laser.
A series of experiments and numerical simulations have been carried out studying the transition between stable and unstable behaviour observed in a mode-locked argon laser when the cavity length is decreased from the optimum value associated with stable operation. Good qualitative agreement is found between the experiments and the numerical simulations, and the pulse characteristics in this

Modern argon lasers remove blue wavelength light, allowing photocoagulation to be achieved at 514 nm which reduces light scatter as well as preventing absorption of the blue 488-nm wavelength by xanthophyll in the macula. The argon laser is a high-gain system. The divergence of the Argon laser is very small. Disadvantages of Argon ion Laser.
av J Zetterberg · Citerat av 7 — laser-induced fluorescence and sub-Doppler polarization spectroscopy of the CH radical. the ruby laser operating as a three-level system that de-excites to the ground vibrational level in the pressure in a jet of methane diluted with argon.
Laser therapies in general, are more precise than other procedures which means the treatment is more focused on the damaged or problematic tissue. An Argon ion laser is a gas laser in which ionized Argon gas is used as the active or lasing medium. Construction of Argon Ion Laser The experimental setup of Ar+ ion laser is shown in the figure : Argon laser lash ablation can be done as an effective office procedure with topical anesthesia.
In many cases, you will need to keep taking glaucoma medications even after ALT surgery.Laser surgery has become increasingly popular as an intermediate step between drugs and traditional glaucoma surgery. 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. ALT is for
Argon laser lash ablation can be done as an effective office procedure with topical anesthesia. The advantages include low recurrence and complication rates in carefully selected patients and minimal postoperative discomfort. Argon laser has very less divergence (about 1 milli radian) like He-Ne laser. Drawbacks or disadvantages of Argon Laser. Following are the drawbacks or disadvantages of Argon Laser: Overall efficiency of argon laser is very less usually between 0.01 to 0.1%.
Disadvantages of Argon ion Laser. The cost of an Argon laser is more than that of a He-Ne laser.

Med LASEK kan vi korrigera synfel ned till -7 och astigmatism (brytningsfel) ned till -6. LASEK är en välbeprövad operationsmetod som används i stor utsträckning över hela världen. Med LASEK kan vi korrigera samma synfel som med FS-LASIK, men läkningstiden är längre och smärtsam. The metastable density produced was higher than 10 12 cm −3, quite enough for efficient laser operation.

The breakup time increased from 9.1 to 10.2 (P = 0.007), but the Schirmer test results did not show any differences after the surgery (P = 0.257). Conclusions: Conjunctivoplasty using an argon green laser is a simple and effective choice to treat symptomatic patients with CCh, especially in cases of mild-to-moderate grade CCh.
ALT is for those: who have been diagnosed with glaucoma The argon laser is used in a number of medical applications which include treatments for various eye conditions, such as glaucoma and diabetic eye disease. Many dermatologists have used argon lasers to treat ulcers, lesions and polyps. Other medical applications include photocoagulation and many ophthalmologic procedures.

This laser is absolutely huge! It Such lasers may either be flashlamp pumped, or more commonly pumped with another laser such as an Argon or Nitrogen laser. To obtain CW reliable operation the dye is made to flow through a thin cell. Using the appropriate dye solutions, an argon-ion laser as a pump, and a prism, the dye laser is tunable across most of the visible spectrum. Fig. 1 Argon ion laser schematic Argon-ion lasers operate in high temperature plasma tubes with bores about 1.2mm diameter, and lengths up to 1.5m. Excitation is by a high current discharge that passes along the length of the tube, concentrated in the small bore. Argon laser therapy utilizes this technology to treat multiple gastrointestinal conditions including hemorrhages, dysphagia, mucosal lesions, and strictures.
