External-cavity feedback can improve the spectral properties of LD or LDB. However  spectrum narrowing of LDB is more difficult than that of LD. Bar curvature (i.e. "smile") produced in the manufacturing process affects the spectrum narrowing greatly. By geometrical optics approach and ORIGIN software  smile which can be corrected by plano-convex cylindrical lens is simulated and the result is in good agreement with experiment. The selection of grating which is also a critical factor of spectrum narrowing will be stated. Finally  an external cavity consisting of fast axis collimator  two plano-convex cylindrical lens and a diffraction grating is used. The scheme is implemented on a 19-element LDB and yields 3-fold reduction in spectral linewidth under the situation that all optical elements in the system which are not optimized. Further  we use a slit in the experiment and analyze the spectrum narrowing of each element in LDB.   Advances in high power semiconductor diode lasers - art. no. 682402 会议论文  OAI收割 conference on semiconductor lasers and applications iii, beijing, peoples r china, nov 12-13, 2007 Ma, XY; Zhong, L 收藏  |  浏览/下载：44/0  |  提交时间：2010/03/09 laser diodes  laser bar  stacks  high power  power conversion efficiency  reliability  packaging   High Efficiency 1.9 kW Single Diode Laser Bar Epitaxially Stacked with a Tunnel Junction 期刊论文  OAI收割 IEEE Photonics Journal 作者:  Zhao, Yuliang;  Wang, Zhenfu;  Demir, Abdullah;  Yang, Guowen;  Ma, Shufang   |  收藏  |  浏览/下载：17/0  |  提交时间：2021/05/08 semiconductor laser  diode laser bar  high power  power conversion efficiency  tunnel junction
