【摘要】 对强脉冲激光照射空阴极放电(HCD)灯阴极产生的非共振光电效应信号的瞬态波形和各种特性进行了实验研究和理论分析.结果表明,这一现象起因于放电灯阴极在强激光照射下的多光子光电发射,因而利用这一效应可以进行多光子光电效应的研究和测量某些放电等离子体参数.利用这一效应并能为解释脉冲光电流效应的机理提供有力的实验证据.更多还原

【Abstract】 The characteristics of nonresonant photoelectric effect signal in a hollow cathode discharge tube irradiated by an intensitive laser pulse have been studied theoretical and experimently. It is shown that this effect can be used to investigate the multipho toelectric effect and to measure the discharged plasma parameters. It is also provided a powerfull experimental demonstration for studying the pulse optogalvanic principle.更多还原
