Abstract

Nonlinear (at the second harmonic frequency of the incident light) optical reflection by two-dimensional hexagonal magnetic bubbles (cylindrical magnetic domains) lattice is theoretically studied. Because the period of this magnetic bubble lattice is comparable with the wavelengths of the fundamental and the second harmonic radiation, it would be possible to observe diffraction at the second harmonic frequency. A polarization analysis of nonlinear diffracted radiation is performed.
