The performance of the Q-switched Nd:YAG laser at 1064 nm has been systematically investigated. 85 kW in a compact cavity with the homemade cryogenically cooled Nd:YAG crystal slab. Topical hydroquinone (HQ) remains to be the first-line therapy. Contact us. Uneven pigment ( brown age spots, freckles, melasma) Seborrhoeic keratosis and other benign skin growth. To minimize the chances of ocular damage, YAG laser treatment was only performed for floaters having a distance longer that 2 mm from the retina and the crystalline lens. Melasma is a common pigmentary disorder with a complex pathogenesis, of which the treatment is challenging. The water absorption coefficient is 12,800/cm. In addition, it can be done on people who have retinal diseases. The treatment is routinely done as an outpatient procedure, typically lasts under 15 minutes and involves no surgical cuts. Materials known as Nd:YAG are crystalline materials of the cubic system made from the neodymium-doped yttrium aluminum garnet, which, among others, have excellent optical properties. " A single bothersome opacity was found in 25 eyes, while multiple opacities were seen in 17 eyes. The laser cutting experiments were carried out using a pulsed Nd:YAG laser (Model JK-704, GSI Lumonics) operated in the LD-1 mode having a fixed average power of 135 W. Researchers say this procedure has a success rate of about 95 percent, meaning it almost always clears your vision. Abstract. Exploiting this in-band pumping scheme, a novel volume-Bragg-grating-locked diode-laser array (DLA) operating at 869 nm was developed to end-pump a cryogenically cooled Nd:YAG crystal. 2% are obtained with 10at. 5.

Laser and light sources represent the mainstay in managing this condition []. with ytterbium, erbium, thulium or holmium doping (see below). The per-session cost varies based on the region of the skin that is to be treated, and the total cost of the treatment varies based on the number of sessions required. A first session with Nd-YAG laser (2,5 mm spot size, fluence 100 J/cm 2, pulse duration 7 ms) for the. Sharp, in Biophotonics for Medical Applications, 2015 4.
