摘要	PURPOSE:To oscillate the infrared laser element stably by desired wavelength by mounting an electronic cooling element between a cooling member and the laser element and controlling current value conducted through the electronic cooling element. CONSTITUTION:A cooler with double structure consisting of an inner pipe 1 and an outer pipe 2 is filled with a liquefied refrigerant such as liquid nitrogen 4 and the cooling member 5 set up at the nose section of the inner pipe 1 is cooled. The elctronic cooling element 6 is fixed at the nose section of the member 5, and the infrared laser element 8 is mounted at the end section. According to such constitution, the temperature of the element 8 can be adjusted by changing the value of currents flowed through the element 6. Consequently, the oscillating frequency of the element 8 can be controlled by varying and controlling the temperature of the element 8 at a temperature close to the temperature of the refrigerant 4.
其他摘要	用途：通过在冷却构件和激光元件之间安装电子冷却元件并控制通过电子冷却元件传导的电流值，使所需波长稳定地振荡红外激光元件。组成：一个由内管1和外管2组成的双层结构的冷却器充满液化制冷剂如液氮4，并冷却设置在内管1的前端部分的冷却件5。电子冷却元件6固定在构件5的前端部分，红外激光元件8安装在端部。根据这种结构，可以通过改变流过元件6的电流值来调节元件8的温度。因此，可以通过改变和控制元件8的温度来控制元件8的振荡频率。温度接近制冷剂4的温度。
