Abstract
A new type calorimeter for precise measurement of 10 W level laser power has been designed and fabricated. This is a double configuration consisting of an absorbing unit made of a disk absorber and an isothermal unit. The ratio of the substituted laser power to the dc power is determined for the absorbing unit. The design of basic construction and experimental results are described
