Abstract

We have measured the optical Kerr susceptibility of liquid carbon diselenide and find its value to be (74 ± 11) × 10^-14 csu, with pump and probe wavelengths of 619 and 579 nm, respectively. This value is approximately three times the Kerr susceptibility of carbon disulfide, and is the largest value reported for a simple liquid. A strong dispersion in Kerr susceptibility is observed as the probe frequency is tuned toward the blue, and is likely due to two-photon near-resonant enhancement from the ¹B₂ state. We also report the visible and ultraviolet absorption spectra and linear refractive index measurements of liquid CSe₂.
