Abstract
The thermally induced optical nonlinearity in a chlorophyll ethanol solution is examined. A theory is presented which shows good agreement with experiment. The theory models an optically thick but physically thin medium whose only heat transport mechanism is conduction. An average n2 was found for the medium which corresponds well with previous results but the thermal medium is shown to be fundamentally different from a Kerr medium.
