摘要：

Two-photon fluorescence (TPF) has been excited in different solutions of rhodamine 6G and rhodamine B with single 30-psec pulses from a Nd:YAG laser at 1.06 μm.Up to incident intensities of 6 × 1028 photons cm−2 sec−1 the TPF intensity showed a quadratic dependence on the photon flux.At higher photon fluxes the TPF intensity increased less than quadratically with the incident intensity.A possible mechanism, not considered previously, for this quenching is stimulated Raman scattering.It was observed that TPF-quenching and stimulated anti-Stokes emission had thresholds in the same power range.© 1979 Optical Society of America.
