摘要

We present a laser-diode-pumped 1.6 mu m single-longitudinal-mode Er: LuAG laser. The intracavity etalons were used as mode selectors for the single-longitudinal-mode operation. The maximum single-longitudinal-mode output power was 153 mW with the wavelength of 1650.2 nm at the pump power of 9.18 W, corresponding to a slope efficiency of 4.3%. The M-2 factor was measured to be 1.07. In addition, by changing the thickness of the etalons, a maximum single-longitudinal-mode output power of 114 mW at 1628.1 nm with a slope efficiency of 3.5% was also achieved. To our knowledge, the intracavity etalons Er: LuAG laser operated at single-longitudinal-mode is being reported for the first time.
