Title: Experimental observation of shielding by a laser-produced plasma

Abstract

The transparency of a plasma produced by irradiating metals in vacuum by laser pulses has been studied, as a function of the laser flux. We record the radiation passing through a small opening in a thin metal target plate. A hole 0.12 mm in diameter is located at the center of the focal spot, the diameter of which is 3 or 0.5 mm. The axis of the hole is parallel to the laser axis and perpendicular to the target surface. The plasma produced by short laser pulses (approximately 30 nsec at half-height) overlaps the hole. The plate thicknesses are 0.15, 0.2, and 0.5 mm for aluminum, copper, and lead, respectively.
