✦ Synopsis

Third-order non-linear susceptibilities have been measured for ethane, propane and n-butane at three wavelengths in the visible region by means of gas-phase electric-field-induced second-harmonic generation (ESHG). The susceptibilities are found to be large and strongly frequency dependent. The possible application of these results to the calibration of the non-resonant background in coherent anti-Stokes Raman scattering (CARS) measurements is discussed.
