摘要：

A compact, closed-circle, high repetition frequency non-chain HF chemical laser is demonstrated based on the electric-discharge ignition mode via self-acting ultraviolet pre-ionization. A pair of asymmetric electrodes defines a 12 mmx17 mmx460 mm discharge volume. The circle gas flow is forced through this discharge volume to flush spent gas and replace it with fresh gas. The circulating gas flow in the vertical direction to the optical axis and the flow rate is 9 m/s. When the total gas pressure is 14 kPa, an average power of 50 W is realized with 100 Hz repetition rate in the gas mixture with mol-fractions of 92% SF6 and 8% C2H6.
