利用康普顿散射实现太赫兹皮秒脉冲的分析

 研究了利用微波与电子束团的康普顿散射实现太赫兹的方法、光子产额和辐射功率。推导出了单个电子产生的太赫兹的光子产额和辐射功率表达式，也推导出了电子束团产生的太赫兹的光子总产额和辐射总功率表达式。结果发现：利用微波与电子束团发生康普顿垂直散射，可以产生太赫兹皮秒脉冲;单个电子产生的太赫兹光子产额与微波功率、微波波长成正比，与微波束截面积成反比;单个电子产生的太赫兹辐射功率与微波功率、电子Lorentz因子的平方成正比，与微波束截面积成反比;电子束团产生的太赫兹光子总产额与微波功率的平方、微波波长的平方成正比，与微波束截面积的平方成反比;电子束团产生的太赫兹辐射总功率与微波功率的平方、微波波长以及电子Lorentz因子的平方成正比，与微波束截面积的平方成反比。

Analysis on picosecond pulses of terahertz radiation using Compton scattering

By using the Compton scattering theory, the generation of picosecond pulses of terahertz radiation has been studied, including the photon yield and radiant power. The results show that picosecond pulses of terahertz radiation are expected to be produced by Compton scattering of microwave photons interacting with electron bunches. The photon yield of a single electron is in direct proportion to the microwave power and wavelength, and in inverse proportion to the sectional area of microwave beam. The radiant power of a single electron is in direct proportion to the microwave power and the square of electron’s Lorentz factor, and in inverse proportion to the sectional area of microwave beam. The photon yield of electron bunch is in direct proportion to the squares of microwave power and wave
