The authors regret that in this article, equation 2 describing the model was presented not correctly in the text. In Eq. 2 instead of [Formula presented] should stand [Formula presented]. and the equation should read as follows: [Formula presented]where f, βopt,i, βIR,i, Li are the modulation frequency, optical absorption coefficient, infrared absorption coefficient, and thickness of the thin film (with index i = 1) and substrate (with i = 2). Moreover, a typing error occurred while transferring the equations for the temperature disibutions ΔT1(f,z,βopt,1) and ΔT2(f,z,βopt,2) from Ref. 1. Instead of the thermal diffusivity αi the complex thermal wave vector, defined as σi(f)=sqrt((i·2·π·f)/αi), should be given in equations 3 and 4. The temperature distributions are described by the following formulas: [Formula presented] The results and conclusions are not influenced by these typing errors, because all calculations were performed using the correct equations. The authors would like to apologize for any inconvenience caused. [1] M. Reichling and H.
