摘要

当以1.1 GHz频率进行强度调制的红外激光辐射入射到压力为0.1 torr的稀薄气体中的导电靶上时,观察到腐蚀等离子体中产生的电流脉冲的微波调制。在激光强度为100gw /cm2时,得到电压幅值为2v的微波信号。在10gw /cm2强度下,激光能量到微波波段的转换效率为2.5 ?10 ? 7。

Generation of microwave current pulses in the erosion plasma of a metallic target by two-frequency laser radiation
When IR laser radiation that is intensity-modulated at a frequency of 1.1 GHz is incident on a conducting target in a rarified gas at a pressure of 0.1 torr, microwave modulation of the current pulses generated in the erosion plasma is observed. A microwave signal with a voltage amplitude of 2 V is obtained at a laser intensity of 100 GW/cm2. The efficiency of the conversion of laser energy to the microwave band at an intensity of 10 GW/cm2 is 2.5 ? 10?7.
