THE EXPERIMENTAL OBSERVATION OF ESCAPING ELECTRONS PRODUCED BY 1.053μm LASER-IRRADIATED PLANAR TARGETS

This paper describes the experiments that 1.053 μm Nd:glass laser irradiates planar targets Au,Ag, Ti and C₈H₈. At different laser intensity we have meas-ured escaping high-energy electron spoctra that generated by abnormal abeorption in plasma. The results show that high-energy tail of hot electron distribution is negligible. The electron energy spoctra can be described by Maxwell distribution. High-energy elec-tron temperature T_h is approximately 30～70keV. The scale between the temperature T_h for planar targets Au,Ti and C₈H₈ and the irradiation intensity I_L is given.
