Abstract

When two beams that are different colors are propagating in a nonlinear medium the refractive index for one beam can be changed by the intensity of the other beam. This effect falls under the general category known as cross phase modulation, which is a mutual coupling between the two beams. This coupling does not necessarily involve power transfer but can cause a redistribution of energy between the two beams. The effect of this induced change in the index of refraction has been called induced focusing, thermal lensing and induced waveguiding. But it all amounts to the same thing, the index of refraction is changed by a pumping beam causing a probe beam propagates differently. Table 1 is a short list of some of the work previously done with this effect. The remainder of this paper consists of a series of experiments demonstrating the effects of pumping beams upon probe beams in semiconductor and semiconductor doped glasses.
