A CW green laser was reported with ceramic Nd:YAG as gain material and KTP crystal as frequency doubler. When the pump power was 21.6 W the 1064 nm fundamental output was 11.3 W corresponding to an optical conversion efficiency of 52.3%. When a type-II cut KTP crystal was inserted in the straight cavity as a frequency doubler the maximum 532 nm green output was 1.86 W and the optical conversion efficiency was 7%. The one-dimensional intensity distribution of the green facula was of Gaussian type and the M2 factor was measured to be 1.7 when the output power was 1 W.
