获取超短波长电磁辐射的新途径

New Approaches for Obtaining Short Wavelength Electromagnetic Radiation

在系统研究运动电子对迎面而来的圆偏振激光脉冲的汤姆逊（Ｔｈｏｍｓｏｎ）散射的基础上，讨论了获取超短波长电磁辐射的两种新方案。其一是利用超强圆偏振激光在具有特定速度的电子的非线性散射所伴随的谐波频率上移，其二是利用激光在相对论电子反向散射所伴随的多普勒（Ｄｏｐｐｌｅｒ）频移。

Based on the investigations of Thomson scattring of moving electrons in the presence of oncoming electromagnetic radiation, two new schemes for obtaining short wavelength electromagnetic radiation have been discussed. One of these is to use the harmonic polarized frequency upshift by the nonlinear Thomson scattering of ultraintense circularly laser from the electrons with a certain velocity. Another is to use the Doppler frequency shift by the opposite direction scattering of ultraintense laser from the relativistic electrons.
