Abstract

The paper demonstrates the possibility of the current increase in laser plasma by more than one order at the preaction of low-energy pulse on the target. The conversion effectivity of 0·32% is obtained at the intensity of the principal pulse of a CO2 laser equal to 4 × 109 W/cm2 and at the residual gas pressure of 10−5 torr.
