بررسی 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...

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.

Tunable subpicosecond dye laser amplified at 1 kHz by a cavity - dumped , Q - switched , and mode - locked Nd : YAG laser

Tunable subpicosecond pulses are generated by synchronously pumping a dye laser with the pulse-compressed and frequency-doubled output of an acousto-optically mode-locked cw Nd:YAG laser. The pulses are amplified at a repetition rate of 1 kHz, using the frequency-doubled output of a cavity-dumped, acousto-optically mode-locked, Qswitched, cw pumped Nd:YAG laser. Amplified transform-limited puls...

Cryotherapy is more effective and faster than Q-switched Nd-YAG laser fordepigmentation in universal vitiligo patients

Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...

Retinal 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...
