近日,由中科院长春光机所发光学及应用国家重点实验室大功率半导体激光器课题组佟存柱研究员承担的,中科院知识创新工程领域前沿项目“大功率高亮度光子晶体激光器及列阵”取得了阶段性进展,他们通过布拉格反射波导结构,成功地将半导体激光快轴(垂直)发散角从40度降低到7.5度,慢轴(水平)
Recently, researcher Tong Tongzhu from the State Key Laboratory of High Power Semiconductor Lasers, Institute of Optics and Applied Optics, Chinese Academy of Sciences, took a leading position in the field of knowledge innovation projects of the Chinese Academy of Sciences. “High-power high-brightness photonic crystal lasers and arrays” In a phased progression, they succeeded in reducing the fast axis (vertical) divergence angle of semiconductor lasers from 40 degrees to 7.5 degrees through the Bragg reflector waveguide structure. The slow axis (horizontal)
