Geometrical theory of nonlinear phase distortion of intense laser beams

Description: Phase distortion arising from whole beam self-focusing of intense laser pulses with arbitrary spatial profiles is treated in the limit of geometrical optics. The constant shape approximation is used to obtain the phase and angular distribution of the geometrical rays in the near field. Conditions for the validity of this approximation are discussed. Geometrical focusing of the aberrated beam is treated for the special case of a beam with axial symmetry. Equations are derived that show both the shift of the focus and the distortion of the intensity distribution that are caused by the nonlinear index of refraction of the optical medium. An illustrative example treats the case of beam distortion in a Nd:Glass amplifier.

Effects of cyclotron radiation in magnetically-confined p-/sup 11/B reactors

Description: Confinement parameters, ntau, are calculated for several possible magnetically-confined p-/sup 11/B reactor configurations using a computer code that evaluates cyclotron radiation emission by electrons and follows the energy distributions of the reactants and products explicitly as they undergo nuclear reactions and both low and high angle scattering. The present treatment of cyclotron radiation assumes a uniform magnetic field and an isotropic plasma. Reflectivity is included as an input parameter. The influence of cyclotron radiation on the energy balance of the various p-/sup 11/B reactor configurations is evaluated and the deviation of the electron distribution from a Maxwellian due to cyclotron radiation emission is studied.
