Abstract
Recent work1–5 has concentrated on fanouttype master oscillator power amplifiers (ΜΟΡΑ) as one promising type of high-power (>0.5 W) coherent source, Tire fanout is obtained, by freespace diffraction in the semiconductor material, and thus, the device necessitates an external spherical lens to obtain a diffraction-limited, collimated beam. Furthermore, since the radiation is vinguided, there are phase-front distortions introduced by refractive-index variations due both to thermal gradients and the injected carriers. As a result, phase corrections via external lenses are drive-dependent.2–4
