High-order Nonlinear Dipole Response Characterized with Extreme-ultraviolet Ellipsometry
Polarization engineering and characterization over a wide spectral range are essential to investigate the symmetry properties in matter and to control light-matter interactions. ATTO-EUV laboratory in NTHU for the first time demonstrates that high- harmonic ellipsometry, using the polarization degree of freedom, is able to unveil the quantum nature of the high-order nonlinear dipole response.
