Gaussian-beam propagation in the bio-optical material bacteriorhodopsin is studied with the consideration of the material's intensity-dependent absorption and refractive-index modulation. The beam-focusing size, focusing position, intensity change in the material, and the dependence of these factors on the incident-beam parameters are simulated.
