Using a single-transverse-mode, fiber-coupled InGaAs laser diode at 976 nm as a pump source, the Yb:GdScO laser delivers 343 mW output power at 1062 nm in the CW regime, which corresponds to a slope efficiency of 52%. Continuous tuning is possible across a wavelength range of 84 nm (1027-1111 nm).

- A new mixed crystal, Yb:Ca(Gd,Y)AlO, has been developed and tested for its growth and laser capabilities, showing promising results for both continuous-wave and mode-locked operations.
- The crystal demonstrated a maximum continuous-wave output power of 347 mW with a high slope efficiency of 48.9%, and its emission wavelength can be tuned over a wide range of 90 nm.
- In mode-locked operation, the crystal produced soliton pulses as short as 35 femtoseconds at a wavelength of 1059.8 nm, achieving an average output power of 51 mW and the potential for higher power with slightly longer pulse durations.
