Abstract
The quality of resonator mirrors still is a limiting factor of beam quality and output power for high power argon ion lasers. To compare the different coating and substrate materials and deposition methods it is necessary to measure the absorption of the mirrors. The absorption is of order 10-4. We use the high intracavity power of an argon ion laser to measure this absorption. An external interferometer records the mirror deformation while the 1aser is in operation. The laser mirror itself performs as a shearing interferometer. From the recorded interferogram we calculate the temperature distribution of the laser mirror and deduct its absorption.
