Q - switched Cryogenically Cooled Yb : YAG Laser
This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
متن کاملExperimental Study of a Flash-lamp Pumped Passively Q-Switched Nd:YAG Laser Using Cr4+:YAG Saturable Absorber
This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...
متن کاملبررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته
هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...

متن کاملRetinal hemorrhage thresholds for Q-switched neodymium-Yag laser exposures.
Thresholds for retinal vitreal and contained hemorrhages were determined for 1064 nm laser light at 30-nsec and 4-nsec pulsewidths. Rhesus monkeys received graded exposures from a neodymium-yag laser onto either the macular or extramacular region of the retina. Contained hemorrhages appeared as concentric ring structures with white punctate centers. The vitreal hemorrhage was characterized by t...
