High power doubly resonant all-intracavity deep blue laser at 447 nm based on sum-frequency-mixing technology
A high power continuous-wave deep blue laser at 447 nm is obtained by using a doubly cavity and a type Π 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 output of 5.7 W at 447 nm with near fundamental mode is obtained, and the beam quality M2 value equals 2.53 in both horizontal and vertical directions at the maximum output power.The power stability is better than 2% at the maximum output power during half an hour.The experimental results show that the intracavity sum-frequency mixing by doubly resonant is an effective method for high power blue laser.
