We demonstrated a laser-diode (LD) end-pumped continuous-wave (CW) tri-wavelength Nd:YAG ceramic laser operating at 1064, 1319 and 1338 nm. For the 1064 nm laser, one of the Nd:YAG polished end faces was used as the output coupler. As references, Nd:YVO(4) and Nd:YAG crystal lasers were also investigated under the same structure. We found that the maximum output power came from Nd:YAG ceramic which was 1.74 W, corresponding an optical conversion efficiency of 16.3%. Using a three mirror cavity, we realized efficient multi-wavelength operation at (4)F(3/2)-(4)F(11/2) and (4)F(3/2)-(4)F(13/2) transitions for Nd:YAG ceramic, simultaneously. The maximum output power was 3.2 W, which included 1064, 1319, and 1338 nm three wavelength, and the optical conversion efficiency was 30%.
