摘要:
A method for absolute two‐photon cross‐section‐value &ggr;2evaluation by means of one‐ and two‐photon fluorescence comparative measurements and using a low‐power, single‐mode cw laser is presented. This method is applied to a rhodamine B solution. The experimental value &ggr;2we obtained is compared with previous experimental data measured by a high‐power laser source.
