Nonlinear absorption in pyran dyes
Tóm tắt
The paper represents the results of nonlinear absorption study for solutions of deciaminomethylenepyran dyes DCM 627 and DCM-684 (yuloidine) at wavelength of 532 nm with 350 ps pulse duration obtained with the use of z-scan technique. It is shown that the induced absorption detected is due to two-photon absorption. Nonlinear and two-photon coefficients of absorption are evaluated. The results of numerical simulation are presented.
