The present calculations show that the application of an external magnetic field can generate additional component of the wakefield suitable for Terahertz (THz) radiation generation in a collisional plasma. Based on the approach of perturbation technique under quasi-static approximation, a study is made on the field of emitted radiation pulses from the wakefield when the super-Gaussian laser beams are used. The field of the radiation becomes stronger when stronger magnetic field is applied and the same is the case for the lasers of higher index.

碰撞等离子体中通过尾场产生的太赫兹辐射强

目前的计算表明,外部磁场的施加可以产生尾波场的附加分量,该分量适合于在碰撞等离子体中产生太赫兹(THz)辐射。基于准静态近似下的摄动技术方法,研究了使用超高斯激光束时来自尾波场的辐射脉冲场。当施加更强的磁场时,辐射场变得更强,对于折射率更高的激光器也是如此。
