摘要

The low-temperature property of ytterbium-doped fiber lasers is quite important in various applications. A fiber laser operating at 1018 nm is fabricated and its gain fiber is cooled to-30 degrees C by the temperature control system enabled on the thermoelectric coolers. The cooling effect of the system is better than that of the water-cooling system. The temperature of fiber core is obtained by an in-situ temperature measurement system based on the optical frequency domain reflectometry. Experimental results show that the output power decreases about 5.7 while the temperature is adjusted from 20 degrees C to-30 degrees C. Meanwhile, the central wavelength and the linewidth change little during the temperature tunning.
