The global electrostatic mode in pair-ion plasmas is discussed for cylindric geometry and for a radially inhomogeneous equilibrium density. In the case of a Gaussian radial density profile, exact analytical eigensolutions are found in terms of the Kummer confluent hypergeometric functions. The mode is identified as a convective cell propagating in the poloidal and axial direction, having at the same time a standing wave structure in the radial direction.

    An on-axis spike in the intensity distribution of a Gaussian laser beam grows rapidly as the beam propagates in a laser-produced plasma. The nonlinearity arises through the ponderomotive force and has a saturating behavior. For ν[sub osc] ∼ v[sub th], the optimum spike radius is...
