Abstract: The intense laser power required to measure nonlinear effects can damage the structures upon measuring. We demonstrate that fast Fourier-transform second-harmonic generation (FFT-SHG) technique provides an elegant solution to obtain polarization patterns of degrading structures. ispartof: Frontiers in optics ispartof: Frontiers in optics date:6 Oct - 10 Oct 2013 status: published
