title: Multiphoton cross-section measurements with low-power cw laser-induced luminescence.
abstract: A new method is presented that yields absolute multiphoton cross-section value gamma(n)(n = 2,3) by comparative one-, two-, and three-photon luminescence measurements and by utilizing low-power single-mode cw lasers. The experiments were performed on different dye solutions. The gamma(2) and gamma(3) experimental values obtained are compared with previous experimental data obtained with high-power laser sources.
