摘要

实验研究了飞秒激光脉冲产生的等离子体灯丝在恒定准均匀电场中的放电动力学。开始放电的发展时间(相对于激光脉冲的放电开始的时间延迟)被测量为等离子体灯丝中恒定电场大小的函数。将实验结果与灯丝放电的数值模拟结果进行了比较。

Dynamics of Discharge Development in a Homogeneous DC Field Initiated by a Plasma Filament Created by a Femtosecond Laser Pulse

Dynamics of a discharge in a constant quasi-homogeneous electric field initiated by a plasma filament created by a femtosecond laser pulse is studied experimentally. The time of development of the initiated discharge (the time delay of discharge onset relative to the laser pulse) is measured as a function of magnitude of the constant electric field in the plasma filament. The obtained experimental dependence is compared with the results of numerical simulations of the discharge in the filament.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
