我们用自己研制的激光水下回波实验样机在水池进行了初次实验。现将回波样机和水池实验情况简述如下:回波实验样机为了进行激光水下回波实验,以便为激光水下应用提供必要的依据,我们在几年工作的基础上,吸取兄弟单位工作中的经验教训,自己设计和研制了实验样机。实验样机的特点是:采用调Q钕玻璃重复频率脉冲激光器,产生1.06微米的光脉冲,经过碘酸锂倍频,变成适合水下传输的5300A°绿光输出;电源采用大功率可控硅交流调压和开关,重复频率可调多信号检测用对绿光较灵敏的GDB-19光电倍增管。
We use our own laser underwater echo experimental prototype in the pool for the first time. Echo prototype and pool experiments are summarized as follows: Echo experimental prototype laser underwater echo experiments in order to provide the necessary basis for laser underwater applications, we work on the basis of a few years, drawing brothers unit work In the lessons learned, designed and developed their own experimental prototype. Experimental prototype is characterized by: the use of Q-switched neodymium glass repetition rate pulsed laser to produce 1.06 micron optical pulse, multiplied by the lithium iodate, into a suitable underwater transmission of 5300A ° green output; power using high-power thyristor AC voltage regulation and switching, adjustable repetition rate Multi-signal detection GDB-19 photomultiplier tube with sensitivity to green light.
