【摘要】 介绍一种新型皮秒脉冲激光器,该激光器由序列脉冲激光的产生、单脉冲激光的选取、放大、倍频和扩束准直等部分组成,激光器的振荡级利用被动锁模染料产生的锁模序列脉冲激光,输出后经过单脉冲选择部分选取出其中的一个单脉冲,此单脉冲再经过激光器放大部分的放大和倍频晶体的倍频后,激光器最终输出能量达到120mj、脉冲宽度为100ps、波长为532nm的单脉冲激光,同时,其输出单脉冲激光的外触发同步精度优于2μs。该激光器满足了某些特殊应用的场合对激光光源的要求。更多还原

【Abstract】 A new picosecond pulse laser consists of a resonator, a single pulse selector, two amplifiers, double frequency crystal, a laser light beam expander and collimator and so on. In order to generate a series of mode-locked pulse laser lights, a passive mode-locked dye cell is used in the resonator. A single pulse laser light is obtained from the series of mode-locked pulse laser lights after they have passed the single pulse-selector. Finally, output of a laser light beam with energy of 120 mj and duration of laser light of 100 ps at wavelength of 532 nm is realized after the single pulse laser light is amplified and doubled in frequency, meanwhile, a out-triggering synchro-precision of better than 2 μs is obtained from the laser.更多还原
