摘要
从有机分子非线性光学效应出发,重点讨论了在激光作用下发生的不同非线性光学过程的特性;结合国内外在光子学领域应用的最新发展动态,讨论了利用这些非线性光学效应在激光限幅、频率上转换材料,三维体相光学存储技术,共焦激光扫描显微技术在生物体中的应用以及红外双光子吸收诱导的光动力效应等在光子学领域的应用。
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.
