Fast Plasma Heating.
Abstract
Refraction of a carbon dioxide laser pulse has been investigated for several radial density profiles in a plasma column. Beam guiding and focusing were observed when the density had a minimum on axis, while the beam was refracted toward the wall for a density maximum on axis. The observed heating of the plasma is consistent with classical inverse bremsstrahlung calculations. A new sensitive optical diagnostic technique for measuring electric and magnetic field distributions interferometrically by means of the Kerr and Faraday effects, respectively, has been developed. Other fast plasma heating investigations concerned exploding wires in large magnetic fields and enhancing the energy transfer to a plasma column by exciting a magnetosonic resonance of the column.
