【Abstract】 The characteristics of different nonlinear optical processes, such as reverse saturable absorption, two-photon absorption and the excited state nonlinear absorption induced by two-photon absorption, were emphatically described based on the dependence of the laser intensities for organic molecular systems. Based on the recent developments of the applications in the photonics, the potential applications in the optical limiting, upconversion lasing, three-dimensional optical data storage, multiphoton confocal microscopies for biological systems, and two-photon photodynamic therapy were discussed.更多还原
