Abstract
We report on the first continuous-wave laser operation of a diode-pumped Nd:GGG single crystal at several emission wavelengths in the 1.33µm spectral domain. Multi-wavelength laser operation at 1324, 1331 and 1337nm with a maximum laser output power of 1.83W and a laser slope efficiency of 28.9% for an output coupler transmission of 2.2% is obtained in the free-running regime. By inserting and tilting a 0.1-mm BK7 glass etalon to modulate the losses inside the laser cavity, single wavelength lasing at 1324nm and 1347nm are also achieved with maximum output powers of about 0.77W and 0.41W as well as laser slope efficiencies of 15.2% and 12.6%, respectively. Further increasing the pump power, based on the position of the etalon leading to the single laser wavelength operation at 1347nm, stable dual-wavelength laser operation is demonstrated at 1337 and 1347nm with a maximum output power of 0.61W.
