Paper Abstract

1 mJ pulse energy with a pulse duration less 300 ps was achieved in Nd+3:YAG/Cr+4:YAG microchip laser. To overcome the polarization instability an output coupler sensitive to polarization was designed, using a multilayer dielectric mirror evaporated on a substrate made of a birefringent calcite crystal. Reflection coefficients for ordinary and extraordinary beams Ro = 53% and Re = 57% were obtained. Subnanosecond laser operating at 1064 nm, 532 nm and 355 nm wavelengths with high output brightness and intensity was constructed.
