Three-Photon Induced Optical Limiting of a Novel Multibranched Nonlinear Chromophore Containing Carbazole Moiety

Abstract:

A novel multibranched nonlinear chromophore containing carbazole moiety，4, 4´, 4´´-tris(9-(3,6-tert-butyl)carbazyl-trans-styryl) -1, 3, 5-triphenylbenzene (TCSTPB)，was synthesized and characterized by 1HNMR and elemental analysis. One-photon absorption in chloroform shows the optical transparent property of the chromophore in the near infrared region. The properties of optical power limiting induced by three-photon absorption (3PA) are demonstrated. Large 3PA coefficients and the corresponding 3PA molecular cross section as high as 10^-74 cm⁶ s² was obtained pumped by picosecond laser pulse at 1.06 μm from nonlinear transmission measurements.
