Paper Abstract

The recoil momentum from a laser light pulse in the intensity range 105 - 107 W/cm2 is experimentally investigated for dielectric and metallic targets as a function of the pressure of the surrounding medium and angle of illumination. An equation with empirical coefficients is obtained for the recoil momentum of illuminated targets. Effects of the screening properties of the erosion jet and the back pressure on the recoil momentum are analyzed as the external pressure is varied. The influence of attenuation of the laser radiation during a plum has been solved on the measurements of the reflection coefficient from an irradiated surface.
