Abstract

This report theoretically and numerically investigates the properties of autofocusing of chip beams based on a more accurate analytical model. It is shown that the refinement of the model made it possible to obtain a caustic of the second type. At the same time, caustics of the first and second types "do not intersect": in two-parameter beams, they are formed in different ranges of values of the exponent; and in three-parameter ones they are formed in the same range, but they are spatially separated.
