Book excerpt: This research program has dealt with the development of efficient and compact sources of visible laser light based on the nonlinear optical conversion of the outputs of diode pumped solid state lasers. Intracavity frequency doubling, frequency doubling of continuous wave single frequency nonplanar ring Nd:YAG lasers in external resonant cavities and single pass doubling of diode pumped Q-switched lasers were studied. Nonlinear materials including lithium diffused lithium niobate, magnesium oxide doped lithium niobate and potassium titanyl phosphate were examined. We obtained 45 mW of cw green light from an monolithic externally resonant cavity constructed of MgO:MiNbO3 pumped by a 200 mW single frequency Nd:YAG laser. This doubler was electro-optically locked into resonance with the laser oscillator and maintained at phasematching temperature by a miniature platinum hybrid heater-sensor element and control circuit. Peak powers LiNbO3 over 200 mW in the green were measured with this doubling device when pumped by a single frequency pulsed 500 mW source.
