Coherence and focusing properties of unstable resonator semiconductor lasers
Abstract
The emission characteristics of unstable resonator semiconductor lasers were measured. The output of an 80-µm-wide laser consists of a diverging beam with a virtual source 5 µm wide located 50 µm behind the laser facet. A high degree of spatial coherence of the laser output was measured, indicating single lateral mode operation for currents I ~< 3 Ith.
