Abstract

An adiabatic laser calorimeter has been developed with a sensitivity of the order of 10^-6cm^-1 with one watt of laser power using a CO₂ laser (9(mu) m to 11(mu) m) in the infrared region. The heat leak by conduction and by radiation from a sample to an inner isothermal enclosure is enough small to be ignored because we succeeded in developing the temperature tracking system between the sample and the enclosure. The total uncertainty of absorption-coefficient measurements is estimated to be 5.4%. The absorption coefficient of a potassium chloride sample #2 was (3.17+/- 0.18)X10^-3cm^-1.
