摘要
建立了"脉冲激光-连续探测光-连续擦除光"的实验系统.在532 nm的调Q脉冲激发光和不同波长的连续探测光作用下,研究了细菌视紫红质(BR)膜的光循环过程中的快速响应特性及各中间态的快速光吸收特性.观察到了微秒量级的快速光开关现象,并分析了激发光脉冲作用结束时,各中间态上细菌视紫红质分子的分布.
Abstract
An experiment system of "pulsed light-continuous probe-light-continuous erasure light" is built. By using modulated Q pulse light of 532 nm and continuous probe light of different wavelengths, fast photoresponse characteristic of photocycle and photoabsorption of different intermediate based on bacteriorhodopsin (BR) film are studied. Microsecond optical switch is observed and BR molecule distributing of different intermediate is analyzed when the exciting pulse is over.
