摘　　要：采用自行设计的“染料脉冲泵浦 +连续泵浦 探测光”的实验系统 ,用几种不同波长的脉冲光和连续光研究了在两束光共同作用下 ,细菌视紫红质膜 (BR)各能态光瞬态吸收动力学过程 ,以及光吸收信号与两束光波长和强度的关系 .The characteristics of instantaneous optical absorption of bacteriorhodopsin (BR) at different wavelengths of dye pulse laser and CW laser beams were investigated with an experimental system of “CW optical pump-probe+dye pulse laser pump”. Especially, the correlation between the optic-absorption kinetic characteristics of BR and the intensity and/or wavelength of CW pump-probe and dye pulse laser was studied.
