🔴 Laser Cavity & Photonics Simulator

Simulate a laser resonator: pump a gain medium above threshold, watch photons build up between two mirrors, and tune output coupling to see laser power emerge.

Pump a laser gain medium above threshold and watch photons build up between two mirrors: tune pump power, output coupling and cavity length to see round-trip gain and output power respond in real time.
