Photo absorption
Web2 Surface Photoabsorption (SPA) Method SPA has been developed as an in situ and surface-sensitive monitoring method used in vapor phase epitaxy. The method is based on optical reflectance measurements using the incidence of p-polarized light near the Brewster angle ( Kobayashi and Horikoshi 1989 ). WebWe present absolute two-photon absorption (2PA) spectra of 15 commercial organic dyes covering an extended range of excitation wavelengths, 550–1600 nm. The 2PA is measured with an estimated accuracy ±10% using a femtosecond fluorescence excitation method. The data are corrected for the variations of the pulse duration and the beam profile with the …
