Monolithic self-Q-switched Cr,Nd:YAG laser.
We report the operation of a diode-pumped monolithic self-Q-switched Cr,Nd:YAG laser in which the codoped ions create saturable absorption for Nd(3+) laser emission at 1064 nm. With a 70-microm beam diameter in the gain medium, the Q-switched pulse has a duration of 3.5 ns and a peak power of 2 kW. The output is linearly polarized with an extinction ratio of 600:1. The pulse-to-pulse intensity ...
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...

We report the operation of a diode-pumped monolithic self-Q-switched Cr,Yb:YAG laser which generates 20 lJ pulses at 1030 nm with a pulse duration of 500 ps in a single longitudinal mode. 2003 Published by Elsevier Science B.V. PACS: 42.55.xi; 42.60.Gd
متن کاملHigh efficient actively Q-switched Ho:LuAG laser.
We present the room temperature Q-switched performances of a Ho:LuAG laser operated at 2.1 microm. At the repetition rate of 10 kHz, the maximum average output power of 9.9 W with a slope efficiency of 69.9% relative to absorbed pump power was obtained in Ho:LuAG laser. Also, the minimum pulse width of 33.0 ns was obtained, corresponding to the peak power was 30.0 kW.
متن کاملClinical applications of Q-switched NdYAG laser.
682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...
