Optical limiting in bacteriorhodopsin using a four-state model for two-beam illumination

Abstract

In this paper we have discussed a four state model in bacteriorhodopsin (bR) for two beam illumination. The paper presents simulation studies showing the change in the population levels of the various states in the bR cycle. The role of M state in the photocycle as a buffer, leads to powerlimiting in the sample. A study of the powerlimiting properties with respect to pump and probe beam intensities has been demonstrated…
