Abstract This paper examines the effect of a density gradient produced in a target by a prepulse on the efficiency of synchrotron gamma-ray generation by a laser pulse with an intensity of the order of 10{sup 22} to 10{sup 23} W cm{sup −2} obliquely incident on a planar target. We demonstrate that the gamma-ray and hard X-ray generation efficiency and the fraction of absorbed laser pulse energy can exceed those in the case of a uniform target with a sharp boundary by a factor of 1.3 – 2, depending on the angle of incidence. At a moderately large preplasma size, the optimal angle of incidence is 30°. At a sufficiently large size, normal incidence is optimal. (paper)
