operated stably after more than 500h. In conclusion, we obtained a nearly round FFP in the 650nm band wavelength using the S3-laser. The laser had good I-L characteristics and good reliability at lOmW and 60°C. We consider that the laser could be of use as a light source in optical disk systems. and TERAMOTO, I.: 'Novel technology for formation of a narrow active layer in buried heterostructure...

BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...

BACKGROUND Nepalese population with Fitzpatrick skin types III-V has high prevalence of pigmentary disorders and it is a growing cosmetic concern. Q-Switched Neodymium- Doped Yttrium Aluminum Garnet (QS Nd-YAG) laser is an efficacious tool in the treatment of pigment disorders. OBJECTIVE To highlight the efficacy and safety profile of various pigment disorders. METHODS A prospective study d...

Single-crystal rare-earth doped YAG fiber lasers grown by the laser-heated pedestal growth technique Report Title High concentrations of the rare-earth elements erbium, holmium and thulium have been successfully doped into single crystal (SC) yttrium aluminum garnet (YAG, Y3Al5O12) fibers by use of the laser heated pedestal growth (LHPG) method. The spontaneous emission spectra and fluorescence...

conclusions the patient reported that he did not feel pain or discomfort throughout the intervention. follow-up visits performed after one, three, six, twelve, and sixteen months demonstrated vitality of the tooth the absence of complications, as well as good esthetic results. laser technology may be used in the treatment of traumatic anterior teeth injury with advantages in terms of quality of...

We present our recent advances in the use of pulsed laser deposition (PLD) to fabricate active gain elements for use as amplifiers and laser oscillators. Record output powers exceeding 16 W and slope efficiencies of 70% are reported for optimized epitaxial growth of Yb(7.5%):YAG on to YAG substrates. We show for the first time that the performance of PLD material can meet or even exceed that of...

BACKGROUND Facial reticular blue veins are of esthetic concern. Most often these veins develop on the lower lids. The safest and most effective way of treatment is by vascular lasers. CASE REPORT We report on a successful reticular vein treatment using a long-pulsed 1064 nm Nd: YAG laser. We present a follow-up of 8 years with constant esthetic improvement without unwanted adverse events. C...

Acute and chronic experiments were carried out in 26 beagle dogs to study the safety and efficacy of Neodymium-Yag laser photocoagulation in the treatment of bleeding gastric lesions. Continuous high power (50-60 W) Neodymium-Yag laser photocoagulation applied to the exposed stomach of the dog produced evaporation lesions that reached the muscle layer after six to 10 seconds and caused free per...

Background: Among various intracorporeal lithotripters, pneumatic lithotripter has become the widely used tool for the treatment of urinary stones. Recently the holmium: YAG laser has been used with a wide range of potential urological applications, including intracorporeal lithotripsy of urinary calculi. Purpose: Compare the effectiveness and complications of treatment for ureteric stones betw...

BACKGROUND AND PURPOSE To establish a less invasive and reproducible focal ischemia model in the rat, we adopted a 2-laser system (ie, photothrombosis and YAG laser-induced reperfusion). METHODS The distal middle cerebral artery (MCA) of spontaneously hypertensive rats was occluded by 568-nm krypton laser and intravenous infusion of the photosensitizing dye rose bengal and was recanalized by ...
