Emission of energetic electrons from a Nd-laser-produced plasma
Abstract
Absolute spectral measurements of 50-500-keV electrons emitted from a Nd-laser-produced plasma are presented. For normally incident irradiation (1015-1016 W/cm2) onto polystyrene slab targets a total emitted energy of ∼1010 electrons is inferred with a total emitted energy of ∼0.2 mJ. The electron emission is observed to be almost the same both in and out of the plane of polarization. Properties of the emitted spectrum, such as spectral hardness and intensity, are observed to be dependent on the pulse shape and the target material.
