| Abstract: | The characteristics of instantaneous optical absorption in bacteriorhodopsin(BR) pumped by different wavelength cw and pulsed light were studied with the experimental system of “cw optical pump-probe+pulse laser pump” designed by ourselves.Especially, a 632.8 nm laser was used as the cw pump-probe light to study the correlation between the optic-absorption kinetic characteristics of BR’s every state during the optical cycle process of proton charge together with its instantaneous optical absorption and the intensity of cw pump-probe or pulsed pump laser. |
