Development of High Power All-Solid-State Red, Green and Blue Lasers

The high power all-solid-state red, green and blue lasers have been developed by means of Q-switched diode side-pumped Nd:YAG laser modules and the intracavity nonlinear frequency conversion in the LBO nonlinear crystals. The red laser generates based on the frequency doubled 1.3 µm Nd:YAG transition, and corresponding maximum output power is 64 W. The green output power of 218 W from frequency doubled 1064 nm Nd:YAG transition have been obtained. The blue laser based on the frequency tripled 1.3 µm Nd:YAG transition delivers the output power of 7.6 W. To best of our knowledge, this is the maximum blue output power for the intracavity frequency tripled 1319 nm Nd:YAG laser.
