Design considerations and operating characteristics of high-power active grating-surface-emitting amplifiers

摘要

An analysis of the characteristics and optimization of the design parameters of active-grating surface emitting amplifiers is presented. It is concluded that coherent power outputs of more than 1 W with >or=30 dB of amplified spontaneous emission noise power contained in the far-field beam divergence of the coherent output are expected for amplifier lengths greater than 0.5 cm. The effects of end reflections on the active-grating amplifier power output are also considered, and it is found that end reflections of 10/sup -3/ or less should have a negligible effect on the power output.
