Spatially coherent diode laser with lenslike media and feedback from straight-toothed gratings |
摘要 |
In a surface emitting semiconductor laser, a variable index of refraction layer having an approximately parabolically shaped trough therein is positioned adjacent the active lasing region and a straight toothed second order diffraction grating coacts with the refraction layer to produce a broad spatially coherent output beam.
