摘要
实验测试了不同吸附剂装填量、不同介质循环速度、不同环境温度与分子筛孔径等实验条件下重频运转的焦级非链式脉冲HF激光器的输出能量变化情况。结果表明,吸附剂3A分子筛的装填量为15kg、介质循环速度为8m·s^-1已满足焦级非链式脉冲HF激光器在50Hz重频下的运行需求,此时,激光器输出1 000个脉冲后的能量下降率约为20%。另外,较高的环境温度有利于提高吸附剂的吸附效果,可改善激光器输出能量的稳定性。在相同的实验条件下,5A分子筛的吸附效果优于3A分子筛。
The output energy of a repetitive,Joule-level,non-chain pulsed HF laser is investigated under the conditions of different loading weights of sorbent,circulating rate of medium,operating temperatures,and apertures of molecular sieve.Experiments show that3 A molecular sieve of 15 kg and the medium circulating velocity of 8 m·s^-1 can meet the requirements of Joule-level,non-chain pulsed HF laser at repetition rate of 50 Hz.The output energy drops about 20% after 1 000 pulses.In addition,a relatively higher room temperature helps to improve the absorption efficiency,leading to a better energy stability of the Joule-level HF laser,and with the same experiment conditions,molecular sieve with an aperture of 5 Ahas better absorption effect than those with an aperture of 3 A.
