Influence of Beam Jitter on Thermal Blooming

Abstract

Laboratory simulation experiments have been carried out to investigate the effects of beam jitter on the thermal blooming of a laser beam propagating in an absorbing medium with a transverse wind. Results obtained with a broadband, low pass white noise jitter frequency spectrum are in good agreement with the root-sum-square approach which considers the jitter and blooming effects to be independent. The effects of beam jitter on the scaling laws for thermal blooming are considered.
