What is dye laser used for?
They are used to treat port-wine stains and other blood vessel disorders, scars and kidney stones. They can be matched to a variety of inks for tattoo removal, as well as a number of other applications. In spectroscopy, dye lasers can be used to study the absorption and emission spectra of various materials.
What lasers are used in ophthalmology?
Uses of LASER in Ophthalmology:
| ANATOMICAL SITE | LASER PROCEDURE | TYPE OF LASER |
|---|---|---|
| ANGLE | Laser trabeculoplasty (ALT) | Argon |
| Selective laser trabeculoplasty (SLT) | Argon | |
| CILIARY BODY | Cyclophotocoagulation (CPC : transscleral/ trans pupillary/ endoscopic) | Diode Nd: YAG |
| ANTERIOR VITREOUS FACE | Laser vitreolysis | Nd: YAG |
What type of laser is used for retinal surgery?
The argon laser is a special, green-wavelength laser that is often used for retinal therapy.
What type of laser is used for photocoagulation?
Photothermal (photocoagulation and photovaporization) Typically, argon, krypton, diode (810nm) and Frequency doubled ND:YAG lasers cause this type of effect. Photovaporization occurs when higher energy laser light is absorbed by the target tissue, resulting in vaporization of both intracellular and extracellular water.
What are the applications of semiconductor laser?
Such characteristics make semiconductor lasers the most important type of lasers, technologically speaking. Their applications are extremely widespread and include optical telecommunications, optical data storage, metrology, spectroscopy, material processing, pumping of other lasers, and medical treatments.
What is the YAG laser used for in ophthalmology?
A YAG laser is used to puncture the anterior capsule peripheral to the IOL optic to allow the trapped material to drain. Alternatively, a posterior capsulotomy can be created to achieve the same result. Anterior capsular contraction syndrome or capsular phimosis may occur with a small capsulorhexis.
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.
What is green laser in ophthalmology?
Laser is nothing but a light of specific wavelength. There are two main type of lasers used in treatment of Retina diseases according to their spectral wavelength i.e. Green and Yellow. Most commonly used laser among the two is called ARGON GREEN LASER. This laser has frequency of 532nm.
What is application of semiconductor?
Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits. Such devices have found wide application because of their compactness, reliability, power efficiency, and low cost.
What are co2 lasers used for?
Carbon dioxide lasers can precisely remove thin layers of skin with minimal damage to the surrounding structures. These lasers treat sun damage, wrinkles, scars, warts, birthmarks and other skin conditions.
Which laser can be seen entering the dye jet?
The pump laser can be seen entering the dye jet, beneath the yellow window. A dye laser is a laser that uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more.
What is the difference between gases and dyes in laser technology?
Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers.
What are the applications of a dotdye laser?
Dye lasers are used in many applications including: astronomy (as laser guide stars), atomic vapor laser isotope separation manufacturing medicine spectroscopy
What are the different types of dye lasers?
Because the liquid medium of a dye laser can fit any shape, there are a multitude of different configurations that can be used. A Fabry–Pérot laser cavity is usually used for flashtube pumped lasers, which consists of two mirrors, which may be flat or curved, mounted parallel to each other with the laser medium in between.
