Abstract
An expression for the energy or power deposited by a Gaussian beam on a decentered circular aperture is derived. It represents a generalization of the classic laser-beam truncation problem, with applications in the areas of laser scanning, detection theory, lidar, free-space communications, and so on. In addition, it can be used to quantify the effect of alignment errors on laser systems.Keywords
