Abstract

We present the first experimental results obtained with a setup created on the basis of the PEARL laser facility for studying the processes of generating terahertz radiation from laser wake fields which are formed during the propagation of a high-power femtosecond laser pulse in a rarefied plasma. In particular, the occurrence of terahertz generation in the case where the laser–plasma interaction region is located between a pair of dielectric prisms of total internal reflection is demonstrated. The dependence of the terahertz radiation energy on the energy of a femtosecond laser pulse and on the plasma density is studied.

超短激光脉冲与气体靶相互作用产生太赫兹辐射的实验研究

我们介绍了在PEARL激光设备的基础上创建的装置获得的第一个实验结果，该装置用于研究从高功率飞秒激光脉冲在稀薄等离子体中传播过程中形成的激光尾流场产生太赫兹辐射的过程。特别是，在激光-等离子体相互作用区域位于一对全内反射的电介质棱镜之间的情况下，太赫兹产生的发生得到了证明。研究了太赫兹辐射能量与飞秒激光脉冲能量和等离子体密度的关系。
