Ultrafast Engine simulates table-top ultrashort-pulse laser systems end to end - from the oscillator to lab diagnostics. It supports dispersion, Kerr/Raman nonlinearity, χ(2) mixing, gain, diffraction, FROG, d-scan, autocorrelators, cameras and more. C# core with Python, C and CLI front ends; plugins for fitting, GPU, HITRAN and Zemax.
