静态气体靶室中氖的高次谐波辐射
High order harmonic generation in neon in static gas target
【摘要】 利用0.5TW的商用飞秒激光器,研究了超短脉冲强激光场中高次谐波辐射,报道了120 fs/795 nm 的Ti:sapphire飞秒激光在静态气体靶室中利用稀有气体氖作为非线性介质的5-17次高次谐波辐射,实验中重点观察了单脉冲能量为38.5 mJ线偏振激光驱动下谐波辐射谱随气压变化情况.
【Abstract】 High-order harmonics in ultra-short intense laser fields by using 0. 5TW commercial fs laser were studied. 5th - 17th harmonic radiation of 120 fs/795 nm Ti:sapphire laser in neon as nonlinear media in static gas target are reported. High harmonic intensities vs gas pressures are investigated with 38. 5 mJ linearly-polarized laser.
