Abstract

PURPOSE: To ensure a laser oscillation with a low current and the lowest stabilized mode and thus to extend further the life time, by specify the direction of the PN-junction of the semiconductor layer composing the PN-junction as well as the mixed crystal ratio of the semiconductor layer surrounding the PN-junction.
