We report on the continuous-wave and tunable laser operation of a transparent Yb:YAG ceramic which is prepared by non-aqueous tape casting method with vacuum sintering at 1750 °C for 10 h. The dense excellent optical in-line transmittance characteristics. In lasing experiment, end-pumped high-brightness 974 nm diode pump in fiber core 50 μm numerical aperture 0.22, results maximum output power 7.01 W slope efficiency 60.2% 1050 nm. A smooth curve from 1022 to 1058 achieved testing, revealing broadband spectra over 30
