In a process for producing a semiconductor laser element, a mask having a pair of openings is formed on a current stopping layer formed above a first cladding layer; a pair of first grooves are formed in the current stopping layer by etching using the mask; portions of the first cladding layer located at the bottoms of the pair of first grooves are etched off so as to form a pair of second grooves in the first cladding layer, and a portion of the current stopping layer left between the pair of first grooves are etched off; the pair of second grooves are filled with a material having a refractive index higher than that of the first cladding layer; and a second cladding layer is formed over the pair of second grooves and the region of the first cladding layer located between the pair of second grooves.

Process for producing semiconductor laser element including S-ARROW structure formed by etching through mask having pair of parallel openings

A solid-state laser module made up of a solid-state laser crystal, a semiconductor laser for pumping purposes, and a resonator mounted on one surface of a mounting plate. A base plate is spaced apart from the mounting plate while facing the opposite side of the mounting plate to the module-mounted side. The base plate and the mounting plate are coupled together by means of at least one coupling member. A temperature control element for controlling the temperature of the solid-state laser module is interposed between the mounting plate and the base plate with elastic adhesive layers between the element and the mounting plate, and between the element and the base plate.
