This proposal seeks a new approach to the problem of improving spatial coherency inlarge volume laser sources, and of coherent combination of the outputs of several lasers.This approach is based on using guided mode grating resonances. A fundamental aspectof this project is the study of mode competition in a laser resonator that contains a newelement: a waveguide grating mirror. This approach is applicable to different kinds oflasers, but it is most advantageous in the case of semiconductor lasers.We expect to improve brightness and high-power semiconductor lasers by a factorof 60 to 100. Potential applications include semiconductor pump lasers, industrial lasersfor cutting and welding, lidars, and vertical cavity surface emitting lasers.

本文提出了一种新的方法来解决提高大体积激光源的空间相干性和多个激光器输出的相干合成问题，这种方法是基于导模光栅共振的。本项目的一个基本方面是研究包含一个新元件：波导光栅镜的激光谐振腔中的模式竞争。这种方法适用于不同类型的激光器，但在半导体激光器的情况下是最有利的。我们预计将提高亮度和高功率半导体激光器的60至100倍。潜在的应用包括半导体泵浦激光器、用于切割和焊接的工业激光器、激光雷达和垂直腔面发射激光器。
