We have measured the spectrally integrated two-photon-absorption (TPA) cross sections for the /sup 4/I/sub 9/2/..-->.. /sup 4/G/sub 7/2/ transitions of Nd/sup 3+/ and obtained values of 1.2 x 10/sup -40/ and 0.15 x 10/sup -40/ cm/sup 4/ for Nd/sup 3+/-doped yttrium aluminum garnet (YAG) and yttrium lithium fluoride (YLF), respectively. These results are in satisfactory agreement with theoretical calculations based on the properties of Nd/sup 3+/ free-ion wave functions. The difference between YAG and YLF, however, is not accounted for by the free-ion theory and suggests that the intermediate-state energies and wave functions are considerably host dependent. In addition, we conclude, based on our measurements, that rare-earth TPA will not contribute significantly to either losses or the nonlinear refractive index in typical laser media employing rare-earth ions.
