Abstract

We present experimental results of temperature tuning in a dual-clad ytterbium fiber laser. We varied the temperature of the fiber from 0 to 100 °C and found significant changes in operating wavelength, power, and threshold. Over this range, the wavelength shifted at a rate of 0.2 nm/°C, and the lasing threshold increased by a factor of 2.
