Abstract

PURPOSE:To draw out only basic mode and made the transverse mode of oscillation single by disposing a reflecting mirror within the rediation angle of light of the basic mode radiated from a laser semiconductor device and providing an antireflection layer at the end part opposite to the reflecting mirror or the laser device.
