Magnetic Field Enhanced Energy Increase of Ions Emitted from Laser Irradiated Solid Targets
A ruby laser adjusted to four different power levels, 6, 9, 15, and 30 Megawatt, was focused to a diameter of 0.1 mm on solid targets (W, Ta, Cr, and A1). A magnetic field of flux density B was applied perpendicular to the target. Hereby the ion energy increased; the increase decreased with increasing laser power. Up to a magnetic field of 2000 gauss and within the range of the laser intensities applied the increase Δε of the kinetic energy ε of the ions followed the relationship: ε3Δε = const B4
