摘要

Abstract

A ground-based laser system for space-debris cleaning will use powerful laser pulses that can self-focus while propagating through the atmosphere. We demonstrate that for the relevant laser parameters

this self-focusing can noticeably decrease the laser intensity on the target. We show that the detrimental effect can be

to a great extent

compensated for by applying the optimal initial beam defocusing. The effect of laser elevation on the system performance is discussed.
