Beam-coupling and interference-induced transparency in a bacteriorhodopsin-based saturable absorber

摘要

Summary form only given. Nonlinear two-beam coupling is a simple and basic tool, used in media with a variety of nonlinear mechanisms, in the study of material and light properties, and in many applications. In this work, we discuss a simple effect of coupling or interference-induced transparency (IIT), which takes place when two beams traverse a nonlinear saturable absorber, made of bacteriorhodopsin, in our experimental demonstration.
