| Abstract: | A single-frequency Tm:YAG laser at room temperature is presented. With two thin etalons as the intra-cavity tuning elements, the maximum output power 69.5 mW is obtained at room temperature. The slope efficiency is 10.2% and the optical to optical conversion efficiency of 4.02%. The central wavelength is 2012.5 nm. A temperature stability of 0.1 °C corresponds to a frequency stability of 74 MHz observed by wave meter in 50 s. |
