摘要 | A laser apparatus and method with compact cavity design that provides suppression of source spontaneous emission (SSE) and amplified spontaneous emission (ASE) light with minimal loss. The laser comprises a gain medium emitting a light beam along an optical path, a tuning element positioned in the optical path and configured feed back light of a selected wavelength to the gain medium and configured to define a first output beam directed along a first output path, a partial reflector located in the optical path and positioned to create a second output beam directed along a second output path substantially parallel to the first output path; and having a spontaneous emission component that is spatially separated from the selected wavelength. The second output beam can be coupled into optical fiber and produce a coherent light source with high spectral purity and tunable wavelengths. |
其他摘要 | 一种具有紧凑腔设计的激光装置和方法,其以最小损耗提供源自发发射(SSE)和放大自发发射(ASE)光的抑制。激光器包括沿光路发射光束的增益介质,位于光路中的调谐元件,并且将选定波长的反馈光配置到增益介质,并配置成限定沿第一输出路径引导的第一输出光束部分反射器,位于光路中,并定位成产生沿基本平行于第一输出路径的第二输出路径引导的第二输出光束;并且具有在空间上与所选波长分离的自发发射分量。第二输出光束可以耦合到光纤中并产生具有高光谱纯度和可调波长的相干光源。 |
