Abstract

Analytical results are presented for the effect of random phase modulated smoothing by spectral dispersion on flow induced laser beam deflection. It is shown that in the limit of a large number of color cycles, N_cc, the effect is identical to that of the induced spatial incoherence method of temporal smoothing. For small N_cc., the beam deflection rate may be significantly larger in the direction perpendicular to the dispersion, than in the parallel direction.
