Abstract
Two-photon absorption from crossed Gaussian laser beams creates a volume grating containing both a primary and a second-order sinusoidal index modulation. Unlike with linear excitation, the two-photon-induced grating exhibits two Bragg diffraction peaks having different decay rates. Comparison of diffracted orders from volume gratings allows the order of the excitation process to be determined.
