【 摘 要 】

Double-pulse nanosecond bichromatic laser irradiation of carbon and brass targets is implemented. The dependence of temperature and density of electrons, as well as the specific recoil momentum of an outflowing plasma jet, on the ordering of laser pulses and the interpulse time delay is found. The results obtained can be used for the development of laser- plasma spacecraft microengines and the enhancement of laser spectral analysis' sensitivity.
