Temporal evolution of output pulse in four-wave mixing

The file shows the temporal evolution of characteristics of the output pulse, including its peak location, peak electric field strength, longitudinal duration and transverse widths along y and z. All quantities are in expressed in standard PIC simulation units, normalised according to reference laser wavelength of 1 micron.本文件展示了输出脉冲各项特性的时域演化过程，包括其峰值位置、峰值电场强度、纵向脉宽以及沿y和z方向的横向宽度。所有物理量均采用标准粒子在单元（Particle-in-Cell, PIC）模拟单位，并以1微米的参考激光波长完成归一化处理。
