中文摘要利用啁啾脉冲放大技术,建成了一台基于钕玻璃放大器1053 nm波长的亚皮秒超短脉冲激光系统(SPS)。系统的输出峰值功率大于20 TW,靶面最高能量可达16 J.采用离轴抛物面反射镜聚焦。在靶面上获得2*10~(18)W/ cm~2的激光功率密度,以此激光脉冲轰击氘化聚苯乙烯平面靶,获得单次发射最高2.4*10~4个中子产额。对中子产生的机理进行了相关的讨论。
英文摘要A Nd:doped-glass-based sub-picosecond laser system with the maximum peak power of greater than 20 tara watts and the energy on target surface of 16 J is accomplished by using the chirped laser pulse amplification technology. While the laser pulse is focused by an off-axis parabolic mirror, the power density on target surface of approximately 2 X 1018 W/cm2 is acquired. In the performed neutron experiment. a C8 D8 plate target is placed on the focal spot of the off-axis parabolic mirror. The maximum neutron yield for a single shot reaches 2. 4 X 10~4. Still some other related problems are discussed. Key words ICF; sub-picosecond ultra short laser pulse; Nd!doped glass based amplifier; neutron yield。
