摘要
We report on diode-pumped continuous-wave Nd:GdYSiO5 lasers, operating on the F-4(3/2) -> I-4(3/2) transition around the 1.3 mu m spectral domain, for the first time to our knowledge. In free-running laser operation, a maximum output power of up to 0.81 W can be obtained at 1357.45 nm with a corresponding slope efficiency of about 10.9%. Wavelength tuning is also realized by using an etalon with a tuning range of about 4 nm. The low-gain emission line at 1386.23 nm is explored with a maximum output power of 0.21 W and a slope efficiency of about 5.3%, using an output coupler coated in a particular way.
