摘要

摘要:研制了高功率、高重频非链式HF 器,并研究了脉冲模式和重频模式下在SF6的混合气中增加电极边缘电场强度而不使用其它措施即可实现自持体引发放电的可能性,得到了重复频率为20 Hz,脉冲能量为67 J,转换效率为3%的输出。

Abstract:The high power nonchain repetitively pulsed HF laser is developed and the possibility of realizing the self-sustained volume discharge in SF6-based mixtures in the discharge gap with a high edge enhancement of the electric field without any additional stabilization measures in a pulsed discharge as well as in pulse-periodic modes is investigated. The obtained laser energy is 67 J at the efficiency in 3% and pulse repetition rate in 20 Hz.
