Webabsorption saturation, we argue that photoinduced intraband absorption also contributes to n 2. Next, using pump-probe four wave mixing (FWM), we determine the time response of the optical nonlinearity. We demonstrate that it contains a nanosecond component at low excitation intensities. With in-creasinglightintensity ... WebMar 8, 2024 · This averages to an overall absorption going to $0$ and therefore the material becomes tranparent. Bleaching is when a material permanently changes its optical …
WebOct 17, 2011 · We measured steady-state photoinduced absorption in trans and in cis-rich (CH)X from 0.1 to 2.5 eV. By assigning the s° optical transitions to the 1.A5 eV band we can fully account for both the bleaching and absorption parts of the spectrum. The e-e correlation energy involved in the soliton defects is found to be ∼ 0.5 eV. http://mol-chem.com/photoinduced_electron_transfer/index.html
