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 10 5 3nm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 2 0TW ,靶面最高能量可达 16J ,采用离轴抛物面反射镜聚焦 ,在靶面上获得 2× 10 18W /cm2 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。
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 2×1018 W/cm2 is acquired. In the performed neutron experiment, a C8D8 plate target is placed on the focal spot of the off-axis parabolic mirror. The maximum neutron yield for a single shot reaches 2.4×104. Still some other related problems are discussed.
