Abstract

Transverse pattern formation was predicted in a laser beam passing through a thin Kerr slice and retroflected by a mirror, provided the intensity slightly exceeds a given threshold.¹ If the laser beam can be approximated with a uniform plane wave, numerical simulation¹ and experiment² showed that the emerging pattern is always a stationary hexagonal array of bright filaments.
