The precise determination of the absolute absorptance of a laser component is of high scientific and commercial importance. Our intention is to demonstrate that laser calorimetry can be a reliable and sensitive characterization tool for this purpose. Furthermore, the limitations of laser calorimetry are discussed and suggestions for possible revisions of the ISO 11551 (International Organization for Standardization, Geneva, Switzerland) standard are made. Finally, laser calorimetry is compared with photothermal deflection methods with respect to their practicability in different fields of laser optic characterization.

  29. A simple method for performing such calibrations is to deposit a high-absorbing coating (e.g., soot or graphite) on a reference sample of identical thermal conductivity, heat capacity, and geometry and test the absorptance with an attenuated laser beam. While high absorptance values can be easily determined with good accuracy (e.g., by spectral photometric methods or by testing transmissivity and scatter), the determination of the attenuation factor is often more difficult, and nonlinearities of the attenuators must be avoided.
