Abstract

PURPOSE:To facilitate the adjustment of the optical axis for infrared laser light, by closely arranging each semiconductor laser element for the radiation of infrared rays and visible light for light emission in the same direction. CONSTITUTION:The infrared ray laser element 3a constituted of PbSnTe is arranged on a cooling stem 1 close to a visible light emission laser element 3b with material of GaAlAs. Two conductive materials 4 on the upper surface of a ceramic plate 2 stuck on the upper left part of the cooling stem 1 and elements 3a, 3b are electrically connected. Next, when the elements 3a, 3b are lighted by passing drive current through the semiconductor laser, visible laser light is radiated from the element 3b in parallel with the laser light from the element 3a so as to set to approximate point by this visible light next to precisely adjust the optical axis for infrared laser light.
