超强Laser场中的非线性辐射压和随机性

Nonlinear Radiation Pressure and Stochasticity in Ultraintense Laser Fields

Joel E. Moore

摘要:

本文计算了在任意波形和极化的高$a$极限下,单电子在超强平面波($a = eE/mcω\sim 1$)中的辐射力,并证明了辐射力与$a^4$成正比。数值计算发现,当磁场不太强时,即使在高$a$极限下,电子在恒定磁场和超强平面波中的回旋运动也是准周期的.强磁场引起电子的高度混沌运动,并通过数值计算确定了参数空间高度混沌区的边界。应用实验和天体物理学进行了简要讨论。

英文摘要:

The radiation force on a single electron in an ultraintense plane wave ($a = eE/mcω\sim 1$) is calculated and shown to be proportional to $a^4$ in the high-$a$ limit for arbitrary waveform and polarization. The cyclotron motion of an electron in a constant magnetic field and an ultraintense plane wave is numerically found to be quasiperiodic even in the high-$a$ limit if the magnetic field is not too strong, as suggested by previous analytical work. A strong magnetic field causes highly chaotic electron motion and the boundary of the highly chaotic region of parameter space is determined numerically. Applications to experiments and astrophysics are briefly discussed.
