LD端面抽运c切Nd：YVO_4自拉曼倍频589nm黄光激光研究
LD end-pumped c-cut Nd：YVO-4 laser at 589 nm generated by sef-Raman conversion and frequency doubling
摘要
Abstract
In this paper we report a LD end-pumped c-cut Nd：YVO4 yellow laser generated by sef-Raman conversion and frequency doubling. A 10-mm-length KTP with critical phase matching （θ=69°, =0°） cut is adopted as a second-harmonic generation. For the lower stimulated-emission cross section of c-cut Nd：YVO4 crystal, the resonator cavity and the coating of crystals are carefully designed to reduce the insert loss and diffraction loss. Finally, at a repetition rate of 10 kHz and an incident pump power of 11.2 W, the average power of yellow light up to 570 mW is achieved, corresponding to an overall diode-yellow conversion efficiency of 5.1% and a slope efficiency of 6.6%. The central wavelength is at 589.17 nm with a width of 0.2 nm, which is well fitted to the sodium D2 resonance radiation.关键词
