Abstract

We introduce a monolithic disk laser design where a whispering-gallery [WG] mode hosts the laser, while the pump is perpendicularly enhanced by exploiting a vertical Fabry–Pérot [FP] resonance. Pump-laser orthogonality here permits the WG laser roundtrip to be 1000 times longer than the FP-pump mode, which accordingly enhances coherency. In this manner, a 1 cm coherency laser diode can pump a 10-meter coherency erbium-based WG laser mode to enable an integrated ultrahigh Q laser. Orthogonal on-chip lasers, electrically pumped using a semiconductor diode, might impact high-Q photonics. Applications include communication, navigation, metrology, and sensing, where foundry-compatible mass-produced ultracoherent emitters are needed.
