Abstract
Non-linear absorption in boric acid glass films with 10(-4) M concentration of fluorescein and rhodamine 6G was measured with beam intensity variation covering six orders of magnitude. The non-linear absorption in these syste ms has been interpreted in terms of the four-level model of saturable absor bers. Optimum values of the film parameters have been obtained. Convergence problems encountered in the numerical solutions were successfully overcome . (C) 2001 Published by Elsevier Science B.V.
