Abstract

PURPOSE: To prevent the enlargement of the gain distribution within a laser, oscillate the laser only at the lowest order lateral mode and expand the linearity of light emission output up to a high excitating power range by defining the relation between a stripe width and the thickness of the layer on the outside region thereof where influent current spreads laterally, at a specified value.
