摘要
提出了由热键合直角棱镜与角锥棱镜构成的非平面环形激光器, 通过将环形磁铁施加到材料为熔融石英的角锥棱镜上, 实现了该激光器的946 nm单频运转。直角棱镜由未掺杂YAG和Nd∶YAG晶体热键合形成, 充当激光增益介质。采用芯径为200 μm, 数值孔径为0.22的光纤耦合半导体激光器进行端面抽运, 得到了160 mW的连续946 nm单频激光输出。
Abstract
A unique non-planar ring cavity consisting of a thermally bonded Porro prism and a corner cube prism is proposed. 946 nm single-frequency operation is achieved in this cavity by applying the ring permanent magnet to the corner cube prism made of fuse silica. The Porro prism by thermally bonded un-doped YAG with Nd∶YAG crystal acts as the laser gain medium. End-pumped by an optical fiber coupled semiconductor laser with core diameter of 200 μm and numerical aperture of 0.22, the maximum continuous output power of 160 mW at 946 nm is obtained.
