A high-power continuous-wave (cw) Nd : YAG laser operating at 946 nm by utilizing a quasi-three-level transition is reported. The laser consists of a composite Nd : YAG rod end pumped by a fiber-coupled diode laser and a simple plane-concave cavity. At an incident pump power of 40.2 W , a maximum cw output of 15.2 W at 946 nm is obtained, achieving a slope efficiency of 45%. To the best of our knowledge, this is the highest output at 946 nm ever generated by diode-pumped Nd : YAG lasers. In addition, at an incident pump power of 15.2 W , a 1.25 W blue output at 473 nm is achieved with a simple compact three-element cavity and a type-I lithium triborate ( LiB 3 O 5 ) crystal as a frequency doubler.
