A method for preventing spatial or spectral beam seeding in a Q-switched laser is described. The Q-switch trigger of the laser is delayed by several laser resonator lifetimes after the end of the pump pulse. In this way, beam seeding is completely eliminated whilst pre-lase is maintained. ...

为什么波长694nm的Q-switched ruby laser(调Q红宝石激光)是目前最为推荐的色斑方法? 科普大作战超话 #色斑# 首先是安全有效,治疗色斑需要保证在对正常组织损伤尽量小的前提下,选择病变组织和正常组织对光吸收差最大的波长。波长是694nm是可见光,黑色素对这种光吸收良好,血红蛋白和胶原相对弱一点。就这一束光而言,...
A Q-switched fibre laser system comprising a doped fibre gain medium 2 that is continuously pumped by a pump source 6. Back reflection within the system is insufficient to support continuous wave lasing because reflection from the output end is suppressed.. A light storage means 8, such as a...
Two equal power independent laser outputs were simultaneously obtained by separate actuation of two adjacent micromirrors with a combined average output power of 125 mW. Pulse durations of 28 ns FWHM at 8.7 kHz repetition frequency and 34 ns FWHM at 7.9 kHz repetition frequency were observed for ...
