半导体激光光源
摘要：
本发明提供一种半导体激光光源，其即便在产生了部件偏差或接合条件偏差的情况下，也能够提高输出特性和可靠性。作为解决手段，半导体激光光源具备半导体激光器(1)和底座(2)。底座(2)具备底座基板(20)、配置于底座基板(20)的上侧的Au层(22)、配置于Au层(22)上面且在外周部在至少除了与半导体激光器(1)的输出端(1a)侧对应的部分外的部分具有阻隔部(23b)的阻隔层(23)、和在阻隔层(23)上面配置于被阻隔部(23b)围起的区域中的焊料层(25)，半导体激光器(1)与阻隔部(23b)的内表面隔开预先设定的间隔，同时，通过焊料层(25)以输出端(1a)从焊料层(25)的与半导体激光器(1)的输出端(1a)侧对应的端部向激光的输出方向突出的状态与底座(2)接合。
摘要（英）：

A semiconductor laser light source includes a semiconductor laser (1), and a sub-mount (2). The sub-mount (2) includes a sub-mount substrate (20), an Au layer (22) placed above the sub-mount substrate (20), a barrier layer (23) which is placed on the Au layer (22) and has a barrier portion (23b) 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 the semiconductor laser (1), and a solder layer (25) placed on the barrier layer in an area surrounded by the barrier portion (23b), wherein the semiconductor laser (1) is bonded to the sub-mount (2) through the solder layer (25), in a state where the semiconductor laser (1) is spaced apart by a predetermined interval from an inner surface of the barrier portion (23b), and further, the output end protrudes, in a direction of output of the laser light, from an end of the solder layer (25) which corresponds to the side of the output end of the semiconductor laser (1).
