Ultrafast optics
Small, self-contained tools for everyday estimates at the optical table. Everything runs in your browser — no install, works offline once loaded.
Peak pump fluence, the fluence distribution sampled by a Gaussian probe, and the probe-weighted average — with 1/e² ↔ FWHM conversion, angle of incidence, and collinear geometry.
Convert between photon energy, wavelength, and frequency using exact SI constants, with selectable units and automatic electromagnetic-spectrum classification.
