Research Progress in Planar Waveguide Lasers
摘要
平面波导激光器是板条激光器与光纤激光器的良好结合体, 其结合了两者的优点且避免了各自的缺点, 极高的宽高比率使流经工作区的一维梯度热流控制了热透镜效应, 同时对横向光束质量具有良好的控制; 通过增加工作区的宽和长可以增大输出功率, 大发散角的抽运光可以被约束在大数值孔径的波导结构中, 激光亮度极高。介绍了平面波导激光器的制备与材料以及发展, 综述了已报道的平面波导激光器相关研究, 并展望了其未来的发展。
Abstract
The planar waveguide lasers are the good combination of slab lasers and fibre lasers, which combine the advantages of both while avoiding their each disadvantages. The high aspect-ratio allowing for efficient one-dimensional heat flow from the active region, leads to controlling the thermal lens effect well and controlling the beam quality excellently. By increasing the width and length of the active-region, the high output power is obtained, and the waveguide structure which has a numerical aperture does a great job in constraining the non-diffraction limited pumping light, leading to the high brightness of the lasers. Introductions about the fabrication, materials and history of planar waveguide lasers are made. The reported studies relating to the planar waveguide lasers are reviewed, and the prospect of the further progress is given.
