D. Seipt, B. Kampfer

AI总结:

本文研究超高强度短脉冲激光与相对论电子非线性康普顿散射的光子谱,通过亚结构平均和稳相近似计算总发射概率,发现脉冲场光子产额可比单色波结果高十倍。

摘要:

我们给出了在强度高达 $a_0\gtrsim 100$、脉冲长度为几个激光周期的脉冲超强激光场中,相对论电子发生非线性康普顿散射所发射光子谱的结果。在超高激光强度下,对微分光子谱的亚结构进行平均是合适的。结合这一处理与稳相近似,可以计算总发射概率。我们发现脉冲场中的光子产额比单色波计算所得结果最多可高出十倍。

英文摘要:

We present results for the photon spectrum emitted in non-linear Compton scattering of pulsed ultra-strong laser fields off relativistic electrons for intensities up to $a_0\gtrsim 100$ and pulse lengths of a few laser cycles. At ultrahigh laser intensity, it is appropriate to average over the sub- structures of the differential photon spectrum. Supplementing this procedure with a stationary phase approximation one can evaluate the total emission probability. We find the photon yield in pulsed fields to be up to a factor of ten larger than results obtained from a monochromatic wave calculation.
