The possibility of modifying the scheme of the previously developed three-channel polarization interferometer and creating a device that allows laser probing of plasma with a femtosecond time resolution is demonstrated. The test experiments with a spark in air generated by a nanosecond laser pulse using a probing pulse with duration of 50 fs are carried out. High-contrast interference plasma images making it possible to reconstruct the profile of an electron plasma concentration in a wide range of changes in the delay of the probing pulse with respect to the forming pulse are obtained.

使用三通道偏振干涉仪的飞秒时间分辨率的激光等离子体诊断探测

演示了修改先前开发的三通道偏振干涉仪的方案并创建允许以飞秒时间分辨率对等离子体进行激光探测的设备的可能性。使用持续时间为50 fs的探测脉冲,对纳秒级激光脉冲在空气中产生的火花进行了测试实验。获得了高对比度的干涉等离子体图像,使得可以在探测脉冲相对于形成脉冲的延迟的宽范围变化中重建电子等离子体浓度的分布。
