摘要
利用超热电子磁谱仪测量了紫外超短脉冲激光与固体等离子体相互作用产生超热电子的能谱,在无预脉冲、激光强度为1017 W/cm2 条件下,紫外超短脉冲激光与固体(Cu)等离子体相互作用产生超热电子的能谱呈双温麦克斯韦分布,超热电子温度为81 keV,激光吸收的主导机制为真空吸收。
The hot electron spectrum was measured by using electron magnetic spectrometer during the interaction of ultrashort UV laser and solid plasmas. Under the condition of prepulse-free and intensity of 1017 W/cm2, the electron spectrum with two temperature Maxwellian distribution was obtained and the temperature of hot electron was 81 keV. The dominant absorption mechanism of laser is vacuum absorption.
