What is a krypton laser used for?
Krypton lasers are used in various ophthalmic procedures and for the coagulation of the retina. Some of the other applications of this laser are in: Forensic medicine. Holography and optical pumping source.
How does a krypton ion laser work?
Krypton laser The laser pumping is done by an electrical discharge. Krypton lasers are widely used in scientific research, and in commercial uses, when the krypton is mixed with argon, it creates a “white-light” lasers, useful for laser light shows.
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 the wavelength of krypton laser?
Krypton lasers produce wavelengths in the yellow (568.2) and red (647.1 nm) parts of the visible spectrum. The krypton red laser offers the advantage of deeper penetration into the choroid, as compared with the argon blue-green laser.
What is krypton fluoride used for?
Apart from photolithography, krypton fluoride lasers are used in nuclear fusion energy research, production of soft X-ray emissions, micromachining of plastics, composite materials, and organic tissues. Since the krypton fluoride laser emits deep ultraviolet radiation it is used in medical surgery and therapy.
Which laser is used in dental surgery?
Diode laser (810-1064 nm) has become very popular in general dentistry because of their small size, low cost, fiber optic delivery and ease of use for minor surgery of oral soft tissue.
What is emission spectra of krypton?
The emission spectra of pure xenon, krypton, and neon are reported over the spectral range of 200 to 900 nm from an enclosed inductively coupled plasma discharge operated at atmospheric pressure and 350 W.
What are five common uses of krypton?
Krypton is used commercially as a filling gas for energy-saving fluorescent lights. It is also used in some flash lamps used for high-speed photography….

Is laser photocoagulation safe?
Laser photocoagulation is both safe and effective in the treatment of retina and glaucoma disorders. The eye is first numbed with special eye drops or other form of local anaesthesia, and the pupil is dilated.
How long does it take eye to heal after laser surgery for retinal tear?
For those that have recently undergone laser surgery for a retinal tear or detachment, the healing process could take anywhere from one week to four weeks. It normally takes a full week for the laser treatment to fully seal the tear and prevent detachment, but things can still go wrong once sealed.
