平凹激光谐振腔及产生高阶模激光的方法

本发明涉及一种平凹激光谐振腔及产生高阶模激光的方法；平凹激光谐振腔含有谐振腔体，谐振腔体内设有平面镜和凹面镜，平面镜或凹面镜的反射面中部设有一个条形不反射区域，条形不反射区域表面设有吸光层；平面镜和凹面镜均为正方形镜片，条形不反射区域的长边与平面镜的一个边平行，或者条形不反射区域的长边在凹面镜的主光轴方向上的投影与凹面镜的一个边平行；产生高阶模激光的方法为：激光器中采用上述平凹激光谐振腔，改变条形不反射区域的宽度，激光器分别发出厄米‑高斯TEM﹑TEM和TEM激光；本发明的平凹激光谐振腔不仅可用来产生高阶模激光，且结构简单﹑成本低，产生高阶模激光的方法输出功能强。
