摘要
介绍了用于二极管泵浦固体激光器声光Q开关的设计、制作及应用。该声光Q开关采用重火石玻璃作声光介质,其互作用长度仅为15mm,衍射效率高达80%,插入损耗仅为8%。通过适当的电路设计,驱动电源电脉冲下降时间为6ns,这样调Q得到的脉冲激光宽度为7.68ns,在10kHz调制频率下,峰值功率达72.9kW。
The design,manufacture and application of the A-O Q-switch for the diode pump solid-state laser are presented in this paper.This A-O Q-swith uses the dense flint glass as the A-O medium.It has an A-O interactive length of 15 mm and the diffraction efficiency is up to 80%,but the insertion loss is only 8%.By desirable circuit design,the fall time of the electric pulse of the drive source is only 6 ns,the pulsed laser width obtained with modulating Q is 7.68 ns and the peak power is 72.9 kW at the modulation frequency of 10 kHz.
