High power doubly resonant all intracavity deep blue laser at 447 nm based on su
A high power continuous-wave deep blue laser at 447 nm is obtained by using a doubly cavity and a type critical phase matching KTP crystal for intracavity sum-frequency-mixing. With the incident pump power of 240 W for the Nd:YAP crystal and 120 W for the other Nd:YAP crystal, the deep blue laser ou
