Kerr effect spectroscopy optically-heterodyned Kerr effect spectroscopy HOKE spectroscopy https://orcid.org/0000-0001-5985-7429 heterodyne optical Kerr effect (HOKE) spectroscopy 2009-05-29T01:05:55Z Spectroscopy where the refractive index change of the sample induced by two polarized laser beams (pump and probe) under the influence of an electric field (the 'optical Kerr effect') is measured. The polarizing filters are rotated slightly, giving rise to a heterodyne at the detector, improving the signal-to-noise ratio compared to optical Kerr effect spectroscopy.
