Measurements of weak absorption of optical coatings for multi- wavelength by photothermal deflection technique
The basic principle of weak absorption measurements performed with photothermal deflection technique is discribed. An experimental setup with multiple pumping lasers has been constructed, the testing procedure and the results of a simple measurement example are presented.
