摘要：

Two-photon absorption coefficient beta and intensity-dependent refractive-index n(2) at a wavelength of 1.06 mu m in hydrogenated amorphous Si films have been evaluated using an imaging-type Z-scan technique. Obtained beta and n(2) are 3000cm/GW and 0.006 cm(2)/GW, which are compared with others and discussed in light of a relation proposed by Sheik-Bahae et al. for crystalline semiconductors. Potential of the film to optical communication devices is pointed out.
