摘要
We report all solid-state, continuous-wave, high-power, deep ultraviolet generation. An intracavity frequency doubled Nd:YAG pumped by fiber-coupled diodes is used to generate high-power green output. Significance of nonlinear coupling and spatial hole burning of two-mode oscillation in the laser is discussed. When the incident 532 nm power on an external resonant doubler was 2.9 W, we generated 1.5 W of continuous-wave 266-nm radiation using a Czochralski-grown beta-BaB2O4. To achieve stable external resonance, a novel voice coil motor actuator is employed with servo bandwidth as large as 50 kHz.
