摘要：

Using the methods of combined interferometry, we obtained new data on the momentum coupling coefficient and conversion efficiency of radiation energy into kinetic energy of a gas-plasma stream during femtosecond laser ablation (tau - 45 fs, lambda - 800 nm) of several metals (Ti, Zr, Mo, Cu) in vacuum (p - 5 x 10(-2) Pa).
