⚡ Chirped-Pulse Amplification: Grating Compressor and Pulse Duration (2D)

Top view of a grating-pair pulse compressor with coloured rays showing how each wavelength takes a different path, next to the stretched and compressed pulse shapes. Set the bandwidth, the grating line density and angle, the separation and the stretcher dispersion, and see the group-delay dispersion, the output duration and the separation that matches the stretcher. The grating equation, the pulse broadening, energy conservation and the matched compressor are checked numerically, with four in-page numerical checks.
