Laser unit
专利汇可以提供Laser unit专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a laser unit which has small size and high reliability by coupling a package for sealing a semiconductor laser to a temperature control unit in a thermally conductive manner and forming a terminal leading hole on the heat absorbing and heat generating surface of the temperature control unit. CONSTITUTION:A semiconductor laser 18 is fixedly bonded to a mount 21 in a package 19 sealed with inert gas. A thermistor 23 for detecting the temperature of the laser 18 is secured to the periphery of the package 19. A terminal 24 for driving the laser 18 is led through a hole 30 formed substatnailly at the center of the heat absorbing surface 25' and heat generating surface 25'' of a temperature control Peltier element 25, and the package base 19' and the element 15 are secured to each other in a thermally conductive state. Further, the element 15 is secured to heat sink fins 26 in a thermally conductive state. When thus constructed, since the temperature control unit having large volume can be separated, a laser unit can be reduced in size and operated in high reliability.，下面是Laser unit专利的具体信息内容。
