得到了群速度色散介质中超短脉冲优美厄米高斯光束的解析解。通过例子,比较了不同传输距离、不同脉冲长度、不同群速度色散系数下超短脉冲优美厄米高斯光束的传输行为。分析了群速度色散体介质中超短脉冲优美厄米高斯光束传输过程中的时空耦合现象,特别是光束边沿的脉冲延迟效应。
The analytical solution of ultra-short pulsed elegant-Hermite-Gaussian beams in group velocity dispersive media is obtained. Through an example, propagation properties of ultra-short pulsed elegant-Hermite-Gaussian beams with different propagation distance, pulse duration, and group velocity dispersion are investigated. The spatiotemporal coupling of ultra-short pulsed elegant-Hermite-Gaussian beams in group velocity dispersive media, especially the pulse delay at the beam periphery, is analyzed.
