放电激励重复频率非链式HF激光器
Discharge pumped repetition-rate non-chain HF laser
摘要
Abstract
Design and performance of a closed cycle, repetitive frequency non-chain HF laser is described. Homogeneous glow discharge is formed with UV pre-ionization and transverse discharge structure. Optimal output parameters of single pulse op-eration are given by investigation of discharge characteristics in SF6 /C2 H6 gas mixture and output characteristics of laser pulse. Operating stability of laser device in repetition-rate mode is researched with different gas flowing velocities, charging voltage and total pressure of gas mixture. It is shown that maximal output energy of laser pulse 0. 6 J and peak power 3 MW are obtained. Total efficiency of laser device is about 2. 4%. When gas mixture circulating with 3. 5 m/s flowing velocity, maximal running fre-quency of 50 Hz is obtained and operating stability keeps well. Under these conditions, each laser pulse of 0. 26 J keeps stable, and average power of laser is about 13 W.关键词
