High-power single-mode diode-pumped Nd:YAG laser using a monolithic nonplanar ring resonator.
A 0.91-W single-frequency diode-pumped Nd:YAG laser at 1.06 microm is demonstrated with a TEM(00) output. We also report a 60% slope efficiency from another nonplanar monolithic ring laser with diffraction-limited, single-frequency, 1.06-microm output. Injection locking of two 0.17-W monolithic nonplanar ring resonators gave 0.34 W of single-mode power. Actively controlled injection locking of two lasers was demonstrated for indefinite periods.
