Generation of Secondary Particles from Subnanosecond Laser Irradiation of Targets at Intensities of 10(16) W cm(-2)
Original language description
Emission of several tens of mA/cm(2) currents carried by MeV-protons is reported for plasmas produced by a beam of the 3-TW kJ-class Prague Asterix Laser System (PALS) focused onto foil targets of various thicknesses. The maximum proton energy of 4.2 MeVis observed at a modest irradiance (I lambda(2) similar to 2 x 10(16) W cm(-2) mu m(2)). According to the maximum ion energy scaling E-M similar to (I lambda(2))(0.4) found for picosecond lasers such a value should be reached at I lambda(2) similar to 3x 10(18) W cm(-2) mu m(2). Enhancement of the maximum proton energy can be explained by nonlinear interaction of the PALS laser beam with the generated plasma. Nonlinear effects also result in enhancement in the yield of fusion neutrons from CD2 plasma.The obtained yield of 4 x 10(5) DD-neutrons per laser energy is comparable to those obtained by the use of ps- and fs-lasers irradiating targets with I lambda(2) similar to 10(19) W cm(-2) mu m(2).
