Abstract
A kilo-Watt-level continuous-wave dual-wavelength dual-end diode-pumped Yb:YAG slab amplifier is experimentally and theoretically demonstrated. A 1.18 kW seed with stable dual-wavelength operation at 1029.6 and 1031.5 nm can be amplified to the maximum output power of 6.56 kW. We also propose a numerical model to characterize the amplifier system including broad spectrum and temperature-dependent effects. The numerical results of power and spectra evolutions show great agreement with our experiment. To the best of our knowledge, this is the dual-wavelength laser with the highest average power, which has great potential in scaling the application scope of dual-wavelength lasers.
