A theoretical model, believed to be novel, that describes simultaneous thermal lens and beam deflection phenomena was experimentally tested. The effect of beam deflection on thermal lens measurements and the effect of the thermal lens on beam deflection measurements were investigated. The experiment confirmed the validity of theoretical predictions for measurements of strongly absorbing samples for which the assumption of an unchanged pump beam in the sample is still valid.
