摘要: A laser output measurement mechanism includes a light splitter that is disposed in a state rotated by a predetermined angle about an optical axis of laser light incident thereon, and that reflects a part of the laser light according to a Fresnel reflectivity that depends on a polarization direction and an incident angle of the laser light at a reflection surface thereof, and a light detector that measures an intensity of the laser light reflected by the light splitter.

摘要: A sub-mount includes a sub-mount substrate, an Au layer placed above the sub-mount substrate, a barrier layer which is placed on the Au layer and has a barrier portion at least in a portion of its outer peripheral portion which is other than a portion corresponding to a side of an output end of a semiconductor laser, and a solder layer placed on the barrier layer in an area surrounded by the barrier portion, wherein the semiconductor laser is bonded to the sub-mount through the solder layer, in a state where the semiconductor laser is spaced apart by a predetermined interval from an inner surface of the barrier portion, and further, the output end protrudes, in a direction of output of the laser light, from an end of the solder layer which corresponds to the side of the output end of the semiconductor laser.
