摘要： PROBLEM TO BE SOLVED: To secure close adhesion of a solid-state laser device and an O ring and at the same time a cooling property in the vicinity of a light projecting face. SOLUTION: The light projecting faces f3 of the front end part and rear end part of a solid-state laser medium are so formed as to intersect the upper and lower surfaces, f1 and f2 , of the laser medium at a right angle, and an O ring 27 is arranged as close to the light projecting face f3 as possible, so that a part of the laser medium projecting from the O ring can be much lessened in length than a conventional one where the light projecting face f3 is tilted. Cooling water can be surely fed near the light projecting faces f3 of the laser medium keeping the O ring in a fixed posture, so that laser beams can be lessened in distortion as much as possible. The crosswise edges of the laser medium are formed like an arc in a front view, the O ring 27 is more enhanced in adhesion to the solid-state laser medium as compared with a case where an O ring 27 is directly mounted on an angular oscillating member, and the O ring 27 hardly suffers local damage.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser and its fabrication method wherein a stepped part is formed on each substrate surface for supporting each of an active region and a mode field region, both substrate surfaces are in a (100) plane, and a slant surface connecting the substrate surfaces forms each of different conductivity type slope surfaces at least a specific angle in the direction (111) A from the substrate surface supporting the active region. SOLUTION: A surface of a p-InP substrate 11 that uses a lattice surface (100) as the substrate surface is etched to form a recessed part, a side wall of which is formed into a slant 11C forming a (311) A surface being a crystal surface parallel to an orientation flat. The slant 11C is constructed at this time to have an off angle of 10 degree or more with respect to the lattice surface (100). A pair of strip shaped SiO2 films are formed ON the first substrate surface 11A. This is used as a mask for selective growth. A semiconductor layer composed of a cladding layer 12, a quantum well active layer 13, and a cladding layer is formed on an exposed surface where the strip-shaped SiO2 films are not formed. At this time, Zn and Se are simultaneosuly doped. Hereby, the cladding layer is formed only on the slope, and can be formed simultaneously.

摘要： PURPOSE: To eliminate the need of forming the internal surface of alight condenser which reflects excitation light from an excitation lamp so that the reflected light can be condensed to a laser medium in an elliptic shape by using ceramic as the material of the condenser. CONSTITUTION: In a ceramic light condenser 4, an excitation lamp 1 and laser medium 2 are positioned closely to each other with a glass plate 3 in between. Since the excitation light 6 from the lamp 1 is diffused and reflected by the internal surface 5 of the condenser 4, the need of forming the internal surface 5 in an elliptic shape is eliminated and, therefore, the positions of the lamp 1 and the medium 2 are not restricted by the shape of the internal surface 5 of the condenser 4. While it is desirable to position the lamp 1 and medium 2 as close as possible when only the excitation efficiency of the medium 2 is taken into consideration, the actual positions of the lamp 1 and medium 2 are designed by taking the deterioration of the spread angle of beams caused by a thermal lens effect, etc., into consideration.
