Abstract

A letter by Mohebi et al. [ Opt. Lett. 13, 649– 651 ( 1988)] claims that the large value of n₂ of CS₂ at 10 μm (2.2 × 10⁻¹⁰ esu) measured by that group is due to electrostriction as opposed to the Kerr effect-induced n₂ of 2.1 × 10⁻¹¹ esu. We compare contributions of different nonlinear mechanisms to n₂ and find that absorption-induced thermal nonlinearity should have been dominant in that experiment.
