7 October 1996 Nonlinear behavior of Zn:tetrabenzporphyrin
Author Affiliations +
The nonlinear transmission of Zn:Tetrabenzporphyrin was measured in a Z-scan setup using 532 nm wavelength laser light with a 13 ns pulse duration. The excited-state absorption cross section, the excited-state refractive index cross section and the linear and nonlinear absorption contribution to a thermal image index change are discussed. The effects of fluorescence and acoustic waves on the nonlinear response of TBP have been determined. Limiter performance was modeled in an f/14 limiter and saturation effects were identified.
