Diode-laser-pumped monolithic Nd:YAG nonplanar ring oscillators produce frequency-stable single-mode output at 1.064 {mu}m. Efficient nonlinear techniques. The use of low loss MgO:LiNbO{sub 3} and novel monolithic cavity designs, where the mirrors are deposited directly on the crystal, has allowed 56% efficient c-w second-harmonic generation and greater than 60% efficient parametric oscillation. A theory of second harmonic generation using an external cavity resonant at the fundamental is presented that extends previous work to include conversion of the resonated wave to the harmonic field. A monolithic MgO:LiNbO{sub 3} doubly resonant optical parametric oscillator (DRO) was operated near degeneracy, pumped by the output of the resonant doubler with the laser-producing relaxation oscillation pulses. A monolithic MgO:LiNbO{sub 3} singly resonant optical parametric oscillator (SRO) was pumped as both a standing wave and a ring geometry resonator by a long-pulse amplified and frequency-doubled laser.
