摘要

研究了溴取代对氮杂-二吡咯烷染料非线性吸收性能的影响。非线性吸收在1200nm、1500nm和1700nm波长处测量，在1200nm处出现双光子激发的激发态吸收，在溴化聚甲基菁中更为明显。

Nonlinear Absorption Measurements of Aza-Borondipyrromethene Dyes by the Z-Scan Method

We studied the effects of bromine substitution on the nonlinear absorption properties of aza-dipyrromethene dyes. Nonlinear absorption is measured at wavelengths of 1200, 1500, and 1700nm At 1200nm, excited-state absorption due to two-photon excitation appears, and it is more pronounced in the brominated polymethine cyanine.
