Description
We study second harmonic generation via nonlinear Raman-Nath diffraction in an optical superlattice that maintains a periodic modulation of the second-order nonlinear coefficient χ⁽²⁾ in transverse direction but undergoes random modulation in longitudinal direction. We show that the random χ⁽²⁾ modulation offers a continuous set of reciprocal lattice vectors to compensate for the phase mismatch of nonlinear Raman-Nath diffraction in the longitudinal direction, leading to more efficient harmonic...[Show more]
