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 R_o = 53% and R_e = 57% were obtained. Subnanosecond laser operating at 1064 nm, 532 nm and 355 nm wavelengths with high output brightness and intensity was constructed.
