Single,composite crystal and ceramic continuous wave(CW) 946-nm Nd:YAG lasers are demonstrated,respectively.The ceramic laser behaves better than the crystal laser.With 5-mm long ceramic,a CW output power of 1.46 W is generated with an optical conversion efficiency of 13.9%,while the slope efficiency is 17.9%.The optimal ceramic length for a 946-nm laser is also calculated.
