The effectively large mirror size in a space telescope may be achieved by swarms of mirrors. In this paper, we present an analysis of such a space telescope, where a swarm of randomized micro-mirrors are combined to achieve the resolution comparable to a primary mirror equivalent to the entire distribution. The recorded speckle patterns, which vary randomly(More)
We believe that the effect observed by Xing et al. is essentially cross-phase modulation. It was inaccurately identified as self-bending of light, which is a self-action effect well known in the literature. This Comment addresses an observed effect that we believe has been inaccurately identified by Xing et al. 1 The reported effect is not self-bending, as(More)
The nonlinear refractive-index (n(2)) spectrum of ZnSe near the band gap (lambda(gap) approximately 450 nm) at 77 K was measured for the first time to our knowledge by using self-bending of a pulsed laser beam. The maximum nonlinearity, n(2) approximately 1.9 x 10(-8) cm(2)/W, measured by us is anomalously large, which cannot be explained by conventional(More)
Continuous-wave self-deflection of an asymmetrical laser beam, with a deflection angle up to eight diffraction widths, and strong attenuation of the on-axis radiation were achieved in a short sodium-vapor cell. We determined that the nonlinear refractive index Deltan varied almost linearly with intensity I, Deltan approximately n(2)I, with n(2) ~ -10(-7)(More)
