Title: Mechanisms of the plasma spatial filter for high-power lasers

We describe mechanisms operating in the plasma spatial filter. Curvature of the critical density surface of the blow-off plasma causes high and intermediate spatial frequencies on the incoming laser beam to be rejected. In addition, time-dependent plasma motions result in the masking of high spatial frequency information on a time-integrated near-field photograph of the beam. Effects on the spectrum of the reflected laser light are evaluated. (AIP)
