20080247432 | Semiconductor Laser Equipment - This invention relates to a semiconductor laser apparatus having a structure to prevent corrosion in a refrigerant flow path of a heat sink and cool stably a semiconductor laser array over a long period. The semiconductor laser apparatus has a semiconductor laser stack, a refrigerant supplier, an insulating piping, and a refrigerant. The refrigerant supplier supplies the refrigerant to the semiconductor laser stack. The refrigerant is comprised of fluorocarbon. The insulating piping is an insulating piping with flexibility. An grounded conductive material is arranged inside the insulating piping. The conductive material operates to remove static electricity generated where the refrigerant flows inside the insulating piping. | 10-09-2008 |

20100202479 | HEAT SINK, LASER APPARATUS PROVIDED WITH SUCH HEAT SINK, AND LASER STACK APPARATUS - A heat sink has a first flat plate, a partition plate, and a second flat plate. The first flat plate has an upper surface in which a first recess is formed. The second flat plate has a lower surface in which a second recess is formed, and an upper surface on which a semiconductor laser element is mounted. These recesses form a part of a refrigerant channel. The partition plate has a lower surface covering the first recess, an upper surface covering the second recess, and at least one through hole having the first recess communicated with the second recess. The first flat plate and the second flat plate both have a first coefficient of thermal expansion. The partition plate has a second coefficient of thermal expansion lower than the first coefficient of thermal expansion. | 08-12-2010 |
