Abstract: PURPOSE:To improve the reliability to environment by providing an optical fiber guide to a laser diode mount stage which is mounted on a main body base so that its position can be changed and fixing the tip of an optical fiber quartz part to the optical fiber guide. CONSTITUTION:The laser diode chip 4 is soldered to the lower side of the laser diode mount stage 7 mounted on the main body base 1 so that its position can be changed, and the optical fiber guide 2 penetrates the higher side and is soldered with silver solder 6. The optical fiber guide 2 penetrates the main body base 1 and is held axially displaceable. The optical fiber 3 penetrates the guide 2 and the tip part of its quartz surface is fixed to the guide 2 by a solder part 5. When the optical fiber 3 is stressed or projected in high- temperature environment, the stress is relieved by the axial displacement of the guide 2 fitted to the laser diode mount stage 7, so neither the fatigue breakage of the fixing solder part 5 of the optical fiber 3 nor the breaking of the optical fiber 3 is caused.
