By using two solid uncoated etalons, we present a diode-pumped linear-polarized single-frequency Tm:YAG laser operating at 2 μm. Placing one 0.1 mm F–P etalon at nearly Brewster angle in the cavity, the linear-polarization laser is achieved. The other 1 mm F–P etalon was turned in the range of very small angle, single-longitudinal-mode (SLM) could be obtained. The maximum output power of linear-polarized single-frequency laser of 60 mW is achieved at the wavelength of 2013 nm. The degree of the polarization is over 30 dB. Long-term frequency stability was also investigated, with the results of wavelength fluctuation about 2.55 × 10−13 m within 3 min and frequency change about 18.86 MHz, corresponding to a frequency stability of 1.27 × 10−7.
