摘要	The present invention suppresses fluctuation of the oscillation wave number of a semiconductor laser element due to being affected by ambient temperature. The present invention is provided with: a semiconductor laser element 2; a temperature adjustment section 32 that adjusts the temperature of the semiconductor laser element 2; a temperature sensor 4 that detects the temperature of the temperature adjustment section 32; and a temperature control device 5 that controls a supply signal to the temperature adjustment section 32 so that the detection temperature of the temperature sensor 4 is a predetermined target temperature. The temperature control device 5 changes the target temperature of the temperature adjustment section 32 corresponding to the supply signal to the temperature adjustment section 32.
其他摘要	本发明抑制了由于受环境温度影响而引起的半导体激光元件的振荡波数的波动。本发明提供：半导体激光元件2;温度调节部分32，调节半导体激光元件2的温度;温度传感器4检测温度调节部分32的温度;温度控制装置5控制向温度调节部分32的供应信号，使得温度传感器4的检测温度是预定的目标温度。温度控制装置5将与供应信号对应的温度调节部32的目标温度改变到温度调节部32。
