Abstract :
An integrative external-enhancement ring cavity has been designed to acquire 461 nm blue light source with high output power. Using a 30-mm-long quasi-phase-matched periodically-poled KTP doubling crystal, we have obtained total more than 210 mW blue light from 287 mW coupling incident power with the net conversion efficiency over 70%.
