Zusammenfassung:We report all solid-state, continuous-wave, high-power, deep ultraviolet generation. An intracavity frequency doubled Nd:YAG laser pumped by fiber-coupled diodes is used to generate the high-power green output. The significance of nonlinear coupling and spatial hole burning of the two-mode oscillations in the laser is discussed. When the incident 532 mn 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 /spl beta/-BaB/sub 2/O/sub 4/. To achieve stable external resonance, a novel voice coil motor actuator is employed with servo bandwidth as large as 50 kHz.< >
