title: Measurement of electronic optical Kerr coefficients.
abstract: We describe a degenerate four-wave mixing technique for measuring optical Kerr coefficients. This technique permits discrimination between fast and slow (thermal) nonlinearities. We report results for a number of long-chain organic materials.
