Absorption enhancement induced by a pump beam of 532 nm in C60 toluene solution has been observed and studied from 560nm to 63Onm, and the absorption cross section of its lowest triplet state has been determined in this wavelength range according to our theoretical model. 相似文献

一、前言光物理和原子分子物理是两个既有区别又有密切联系的学科.原子分子是物质组成的一个基本层次.原子分子物理学是研究这一层次的结构、运动状态及与周围环境和外界条件相互作用的科学.光学是研究光的基本性质,光的产生、传输、接收、显示及其与物质相互作用的科学.随着光学的发展和应用领域的日益扩大,比较偏重应用和技术的部分已逐渐脱离物理学而成为独立的科学技术门类. 相似文献

A theoretical model for formation of light-induced gratings in organic photoisomers is presented. Using this model, dynamic behaviors of the light-induced gratings are studied theoretically for two different cases: in the first case, in addition to a CW loser generating the writing beams and the reading beam, a pulsed laser is used as an optical pump, in the second case, the writing beams are provided by a pulsed laser, and the reading beam comes from a CW laser. Agreement between experiment and theory is also demonstrated. 相似文献
