The effect of self-focusing on laser space-debris cleaning

Rubenchik, Alexander M., Fedoruk, Michail P. and Turitsyn, Sergei K. (2014). The effect of self-focusing on laser space-debris cleaning. Light, 3 (4), e159.


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.
