摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser-excited solid-state laser device which can be uniformed in an excitation intensity distribution in a cross section perpendicular to the central axis line of a laser rod. SOLUTION: In the solid-state laser device 1, excitation light L from each LD stack 4 is absorbed by the laser rod 2 so that the intensity I(R) of the excitation light L at the center P 1 of the laser rod may be I 0 /N 0 /N, and the intensity I(2R) at a position P 2 opposite from the entrance side of the laser rod 2 may be 0 0 . Since the number of the LD stacks 4 is N(=6), the intensity of the superimposed excitation light of the excitation lights from all the LD stacks 4 is N(=6) times larger than I(R) at the center P 1 . The LD stacks 4 are located at equal intervals on the circumference of the laser rod 2 so that the width of the excitation light L which has reached the laser rod 2 may be equal to the diameter of the laser rod 2. Due to this structure, the excitation intensity distribution can be uniformed. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：解决的问题：提供一种能够在垂直于激光棒的中心轴线的截面中以激发强度分布均匀的半导体激光激光固态激光器件。解决方案：在固体激光装置1中，来自每个LD堆叠4的激发光L被激光棒2吸收，使得在中心P 1处的激发光L的强度I（R）激光棒的强度I（2R）可以是P <0 / 与激光棒2的入射侧相对的 2 可以是0 0 。由于LD堆叠4的数量为N（= 6），所以LD堆叠4的激发光的叠加激发光的强度比中心P 1的I（R）大N（= 6）倍， SB> 1 。 LD叠层4在激光棒2的圆周上以相等的间隔设置，使得到达激光棒2的激发光L的宽度可以等于激光棒2的直径。由于这种结构，激发强度分布可以均匀。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser system which facilitates position adjustment of a condenser lens section to a semiconductor laser array. SOLUTION: The semiconductor laser system 1 is devised to enable the position adjustment of the condenser lens section F with respect to the semiconductor laser array A arrayed with a plurality of laser exit points P and the condenser lens section F is fixed onto a movable platform 17 in order to facilitate the position adjustment of the condenser lens section F. Also, the fine adjustment of the movable platform 17 meeting the amount of rotational movement of a first adjusting screw 22 is made possible by utilizing the first adjusting screw 22 extending in a direction orthogonal with an optical axis L of a laser beam. The position adjustment of the condenser lens section F with respect to the semiconductor laser array A is thus facilitated. Also, the exact optical axis alignment of the condenser lens section F with respect to the semiconductor laser array A is made possible by mounting the movable platform 17 fixed with the condenser lens section F and the semiconductor laser array A on the same base B.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser device and a method for cooling the same, in which, particularly, a free coolant path layout is achieved, an a coolant discharged from a heat sink is effectively used. SOLUTION: In a cooling method used in a semiconductor device 1 that includes a semiconductor laser array 3 in which a plurality of outgoing laser points 3a are arranged along the longitudinal direction of a front 5; and semiconductor laser units 4 stacked in a plurality of stages having heat sinks 2 that have coolant paths S therein, a gas coolant such as air or a nitrogen gas coolant flows through the coolant paths S in the heat sinks 2, and the gas coolant S is not circulated in a device different from a water-cooling type, but discharged from the heat sinks 2 to the outside. As the result of using such a method, accurate countermeasures against the leakage of the coolant as in the water-cooling type are not required, thereby a free coolant path layout is achieved. Moreover, the semiconductor laser array 3 itself is directly cooled by the coolant for the effective use of the coolant discharged from the heat sinks 2. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a laser device capable of generating a laser beam causing less processing failures. SOLUTION: The laser device comprises two or more light sources 11a-11c containing laser array stacks 12a-12c. Laser beams 32b and 32c are deflected by a slit mirror and a polarization beam splitter, respectively, and are compounded with a laser beam 32a. These laser beams have mutually an inclined axis and mutually parallel slow axis direction. A condensing optical system 20 condenses a laser beam from each light source to a position distant along a direction perpendicular to the slow axis direction. By this way, a laser beam is obtained which has an intensity profile of a top hat type along a direction perpendicular to the slow axis direction. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser device which can improve the condensing efficiency by keeping a constant interval between a laser emitting plane and a condenser lens. SOLUTION: A condenser lens 15 is positioned so as to keep a constant interval between a flat plane 20c of a condenser lens 15 and a laser emitting plane 20a of a semiconductor laser array 11 in a semiconductor laser device 1. After that, a rigid body spacer 18 is inserted while being in contact with the flat plane 20c and a plane 20b supporting a heat sink 14. As an adhesive agent 17 of ultraviolet ray curing type is applied around the rigid body spacer 18, the condenser lens 15 is bonded on the supporting plane 20b by projecting the ultraviolet ray. Thus, the constant interval between the laser emitting plane 20a and the condenser lens 15 can be maintained even if the polymerization shrinkage happens to the adhesive agent 17 by bonding the condenser lens 15 while keeping the rigid body spacer 18 inserted.

The parallel luminous fluxes emitted from the light source 21 are reflected by the respective light reflection surfaces 471 to 476 and are condensed by a simple condenser lens or the like. According to the optical device, the fine processing of the light reflection surfaces is facilitated and the discrete regulation of the positions of the respective light reflection surfaces is made possible in correspondence to the respective parallel luminous fluxes. The detrimental return light does arise in the light source.
