In the paper we are presenting the experimental results of the blue-laser generation by nonlinear frequency conversion of Nd3+:YAG laser on the 1,34 µm wavelength. Blue radi- ation at the wavelength of 0,446 µm was realized by sum-frequency oscillation under nonlinear mixing of radiation at wavelengths of the main (1,34 μm) and the second (0,67 μm) harmonics in DKDP crystal. It is shown that pulse energy of the blue radiation achieved 2 mJ with pulse duration of 20 ns and conversion efficiency of 2 %.

Keywords: blue radiation, YAG:Nd3+-laser, sum-frequency oscillation.
