Nonlinear and multi-photon light-matter interactions are routinely orders of magnitude more sensitive to chirality than absorbance circular dichroism. In contrast to absorbance CD, chiral effects in nonlinear optical interactions are often fully electric dipole allowed, such that chiral-specific responses can be on par with the achiral responses. Molecular-level understanding of the interactions driving these effects provides a foundation for development of new applications for chiral-specific spectroscopy and microscopy. Progress over the past 20 years on both fronts (fundamental understanding and the practical applications it has enabled) will be reviewed, along with an assessment of ongoing and future developments in the field.
