衍射光学激光共振腔所有商品激光器都用球面或平面镜来建立激光模。但球面镜腔只代表极小一组可能的共振腔结构。最近，衍射光学技术已有可能制作具有任意相位反射系数的优质反射镜，从而出现一组全新激光共振腔。这些新腔可有独特和所希望的性质，如用户可设计的模式形状... Diffraction Optical Laser Resonators All commercial lasers use spherical or plane mirrors to create a laser mode. However, spherical mirrors represent only a small group of possible resonator configurations. Recently, diffractive optics have made it possible to produce high quality mirrors with an arbitrary phase reflection coefficient, resulting in a new class of laser resonators. These new cavities can have unique and desirable properties like user-designed pattern shapes ...
