โฆ Synopsis
A diode-pumped single frequency Tm:YAG laser operating at 2 ฮผm is demonstrated in this letter. The laser crystal is controlled at room temperature by using a thermoelectric cooler. Two solid uncoated fused silica etalons are employed to narrow the laser line-width, the thicknesses of which are 0.1 mm and 1 mm, respectively. By tuning the angle of the etalons, single frequency laser is achieved and the oscillating wavelength can be changed from 2008 nm to 2021 nm. And at each wavelength, single-frequency laser is achieved. The maximum single frequency laser power is up to 75.0 mW with the central wavelength of 2013.9 nm. To our knowledge, this is the first time to obtain single-frequency Tm:YAG laser of 75.0 mW with F-P etalons in the cavity. FSR = 3.75 GHz Voltage, V Output power, a.u.
