The processes of electron-positron pairs generation induced by laser radiation of 10{sup 18}-10{sup 20} W/cm{sup 2} are studied. The results of pairs production in Coulomb field of nucleus by relativistic electrons are presented. The estimations of positrons generation and yield from targets considering production from electrons and bremsstrahlung photons are made. The PRIZMA-code simulations performed using Monte-Carlo method confirm the estimations. The positrons yield of 10{sup 8}-10{sup 10} from high-Z targets irradiated by picosecond lasers of power 10{sup 2}-10{sup 3} TW is found to be possible.
