Abstract
An investigation is made of a perturbation in the vicinity of focal points over a laboratory path of a laser beam used in the processing of materials. The following situations are considered: a beam emerges from a focal point and expands; horizontal and vertical beams focused on a control surface. R igorous numerical solutions are obtained of the aero-optics equations descr ibing beam perturbations in front and behind the focal plane. The results a re compared with the experimental data.
