We present a study of -like 1s2-1s2p line emission from solid and low-density targets under laser pulse irradiation with a frequency doubled :Sapphire laser. By varying the beam spot, the intensity on target was varied from to . At best focus, low density “smoked” targets yield times more -α than the foil targets when irradiated at an angle of with s-polarized pulses. The duration of -α emission from smoked targets, measured with a fast streak camera, was similar to that from foils.
