Abstract. A new compact laser based on Nd:YAG crystals is presented. The developed laser generates light pulses with energy up to 800 mJ at the wavelength of 1064 nm; pulse duration comprises 3—5 ns, and the beam divergence is 0.6 mrad. Overall dimensions of the laser do not exceed 200´50´40 mm. Comparison of preliminary computer modeling results with experimental data shows a good agreement.
