Abstract

The invention provides a single-longitudinal-mode optical parametric oscillation amplifier which is extra narrow in bandwidth, ultra in frequency stabilization, tunable and efficient. An optical parameter laser is a solid laser pump injected with seed light, the oscillator stage is of an annular cavity structure design, continuous stable single-longitudinal-mode seed light is injected, and cavity length mode locking is automatically controlled through programs. The optical parameter laser can output single longitudinal mode lasers with the bandwidth smaller than 200MHz, the energy conversion efficiency is close to 40% to the maximum extent, and the output wave length can cover 430-3500nm (limited by the range of seed light wave length). Stabilization of the wave length of the laser and continuous scanning of wave lengths of the seed light within a limitation of non-mode-jump by controlling a self-feedback system through programs can be achieved.
