摘要
We measure the Kerr-nonlinear index of refraction of a three-level Lambda -type atomic system inside an optical ring cavity. The Kerr nonlinearity is modified-and greatly enhanced near atomic resonant conditions for both probe and coupling beams. The Kerr nonlinear coefficient n(2) changes sign when tli coupling beam frequency detuning switches sign, which can lead to interesting applications in optical devices such as all-optical switches.
