In this paper the experimental results of laser multiphoton ionization of background gases (mostly oil-vapor) in the vacuum chamber for laser produced plasma study are presented by using high power laser irradiation.

本文报道了在高功率密度激光辐照下，激光等离子体研究用的真空室中背景气体(主要是真空系统中的油蒸气)的多光子电离的实验研究结果。

High-order harmonic radiation with noble gas and N〓 in static gas target has been obtained, and the effects on high-order harmonic efficiencies due to laser intensities , polarization, gas densities, confocal parameter, media characteristic and phase mismatch have been discussed. The experimental results show that the high-order intensities grow with the incident laser intensities and gas densities, and high-order harmonic signals amplify in the same time.

高次谐波辐射是强场物理中与电离过程相伴而生另一种重要过程，本文利用飞秒激光在静态气室中获得全部的稀有气体原子以及氮双原子分子5到21次的谐波发射，着重讨论了激光功率密度、激光偏振、气体密度、共焦参数、介质本身以及相位失配对高次谐波转换效率的影响。
