Abstract

We report on the development of a laser calorimeter with sub ppm sensitivity. Besides the adaptation of the sample holder for low loss measurements, different ways of evaluating calorimetric data and methods for the detection and compensation of scatter irradiation effects as well as other signal distortions are discussed. As laser sources, an AR- laser and a Nd-YAG laser with frequency doubling option are employed for the measurements. The system is used for the characterization of different types of KTP crystals for frequency conversion. The results show a distinct polarization dependency of the absorption, throughout all crystals investigated.
