摘要
报道了 12 0fs/ 795nm的Ti∶sapphire飞秒激光在静态气体靶室中利用稀有气体氩作为非线性介质的高次谐波辐射 ,在静态靶室中获得高次谐波辐射 ,较常用的气体喷嘴具有结构简单 ,实验容易操作等优点 ,实验中在 4 2mJ和 7.
High-order harmonics of 120 fs/795 nm Ti∶sapphire laser in Ar in static gas target are reported. Compared with the traditional gas target, static gas target is simple in experimental configuration and experimental parameters can be easily controlled. Changes of high-order harmonic intensities vs gas pressures are observed with 42 mJ and 7.5 mJ linearly-polarized laser.
