A diode-pumped dual-wavelength CW Tm, Ho: YAG ceramic laser was demonstrated for the first time to our knowledge. A maximum output power of ~1.2 W with a beam quality factor M2 = 1.19 has been generated from the 3at.% Tm, 0.5at.% Ho: YAG ceramic, corresponding to a slope efficiency of 16.7% with respect to the absorbed pump power. This Tm, Ho: YAG ceramic laser operated at dual-wavelengths around 2090 and 2096 nm. With the increase in the absorbed pump power and the output coupler transmittance, blue-shift of the emission wavelength was observed.
