Laser performance of diode-pumped continuous-wave Nd:CaLaGa3O7 laser with a 22-nm wavelength tunability
Source abstract
Abstract
Abstract We report on the laser performance of diode-pumped continuous-wave Nd:CaLaGa3O7 laser after registering the polarized absorption and emission spectra, for the first time to our knowledge. A maximum output power of 1.45 W is reached at 1061.7 nm and 1067.8 nm with a slope efficiency of about 27.7% with respect to the absorbed power. Wavelength tuning is also realized with a range of about 22 nm using an intracavity un-doped YAG etalon. The broadband Nd3+-doped crystal could be very promising for ultrashort pulse laser generation in femtosecond time duration through mode locking technology.
