| 英文摘要 | PURPOSE:To reduce the area occupied by a laser device on a substrate, miniatuarize the device and increase the output by providing a laser oscillating main body on the front side of the substrate and providing a detecting element on the rear side. CONSTITUTION:Since a first and a second totally reflecting edge planes 80 and 82 provided at both edges of the horizontal activating waveguide 68 of a laser oscillator main body 60 are inclined at 45 deg. to the top plane of a substrate 50, an incident angle of laser beams through the horizontal activating waveguide 68 becomes 45 deg. and the planes 80 and 82 become totally reflecting mirrors for the laser beams. An oscillator is constituted between an injecting window 74 provided at the top of a top side clad layer 70 and a multi-layer reflecting film 64 provided on the bottom side of a bottom side clad layer 66, light generated in the horizontal activating waveguide 68 is amplified in the resonator and laser is emitted from the injecting window 74 to the side opposite to the substrate plane at high output. Since a hole is provided at the bottom of the first totally reflecting edge plane 80 from the bottom plane of the substrate 50 and the hole is provided with an detecting element 90, the detecting element 90 detects the beams permiated through the multi-layer reflecting film 64 when the laser is oscillated and the lased light is monitored. |
