Abstract:
The interference pattern from one-dimensional on-axis null beams subject to nonstationary thermal blooming in a moving transparent or absorbing medium is examined. In the case of optical propagation through a cloudy medium a noninteracting subbeam structure is found to form, which can deteriorate the performance of the adaptive autofocusing system. It is shown that the thermal blooming effect may result in a beam with a single intensity peak if the initial optical power is above a certain critical value.
