Experimental Study on Output Energy Stability of Discharge-initiated Repetition Rate HF laser

摘要

The output energy stability of discharged-pumped pulsed HF laser in repetition rate mode is studied experimentally, and the optimal operating conditions are obtained. The experimental results show that the output energy decreases quickly with the increase of repetition rate, and increasing gas flow rate is beneficial to improve the discharge stability and the output energy stability as well. By optimizing the operating conditions, the laser can operate stably at the repetition rate of 50 Hz, with the stable output energy of about 260 mJ, and the average power is about 13 W.
