摘要: 报道了LD纵向泵浦Nd:YVO4晶体，经腔内和频得到593 nm激光输出的实验研究。采用一个线性平凹腔实现了1 064 nm和1 342 nm双波长连续波振荡，利用LBO腔内和频产生593 nm激光输出。在泵浦功率为1.4 W时得到593 nm的输出功率为70 mW。593 nm光束远场发散角小于1 mrad，光斑椭圆度为0.999，且具有低噪声输出特性。实验结果表明，该结构激光器是获得衍射极限全固体黄激光器的实用方法。Abstract: An LD-end-pumped Nd:YVO4 crystal 593 nm yellow laser by intracavity sum-frequency mixing (SFM) is reported. With one plane-curved cavity dual-wavelength operation, 1 064 nm and 1 342 nm, is realized. By LBO Intracavity SFM 593 nm laser is attained. With 1.4 W pump power 70 mW output power at 593 nm was observed. The far field divergence angle of 593 nm is less than 1 mrad and the ellipticity of the output beam is 0.999. Low-noise characteristic has been proved at the same time. The experiment show that this is the useful method to obtain solid state yellow laser with diffraction limit.
