基于FORTRAN的组合圆偏振激光场下电子动量分布仿真

Electronic Momentum Distribution Simulation Based on FORTRAN by Combined Circular Polarization Laser Field

基于FORTRAN语言编程,通过对二维含时薛定谔方程数值求解,计算机数值模拟氦离子在两束圆偏振激光脉冲组成的激光场下的光电子动量分布。模拟结果发现光电子动量分布受激光场中两束激光脉冲波长和旋向的影响。

Based on FORTRAN language programming,by numerically solving the two-dimensional time-dependent Schrodinger equation,the computer numerically simulates the photoelectron momentum distribution of helium ions by the laser field composed of two circular polarization laser pulses.Simulations found that the photoelectron momentum distribution was affected by the wavelength and polarization direction of the two laser pulses in the laser field.
