Abstract :
Solid-state blue-laser generation by nonlinear frequency conversion of the 1.338-μm Nd:YAG laser MOPA system is experimentally investigated. The 0.446-μm blue radiation is obtained by frequency-tripling technique as the frequency doubling (0.669 μm) with the sum-frequency oscillation (1.338 μm + 0.669 μm). The blue laser pulse output energy of 2 mJ with 20-ns duration and 2-% conversion efficiency is achieved allowing for laser power scaling.
