Topological high-harmonic spectroscopy Harmonics produced when structured lasers hit isotropic targets inherit the topological properties of the driver, but such properties become more complex in the case of anisotropic nonlinear targets. The authors exploit topological analysis of the high-order harmonics to spatially resolve the information about the nonlinear response of the target. Ana GarcĂ­a-CabreraRoberto Boyero-GarcĂ­aCarlos…
