摘要

We experimentally demonstrate a continuous-wave (CW) dual-wavelength emission from a single Yb:YAG thin-disk laser (TDL). Using two grating-waveguide structures (GWS) with high diffraction efficiency allowed to tune the separation of the two spectral emission lines. The dual-wavelength output powers exceeded 42 W for wavelength separations ∆λ ranging between 3.8 and 25 nm.
