摘要：

We demonstrated a cryogenically cooled Yb:KGd(WO4)(2) (Yb:KGW) oscillator. At 77 K, a maximum continuous-wave (CW) output power of 10 W with an optical-to-optical efficiency of 69.4% was achieved. The tuned wavelength bandwidth was 5.9 nm at Nm-polarization and 7.7 nm at Np-polarization, which shows the potential for the broadband amplification. Mode-locked pulses were obtained at a 74.4 MHz repetition rate, where the corresponding wavelength was 1020.4 nm, with a spectral bandwidth of 0.148 nm. This is the first experimental demonstrated cryogenically cooled Yb:KGW oscillator, as far as we know.
