Abstract
A new type of laser calorimeter has been developed which provides high measurement sensitivity and accuracy over several decades of input radiation intensity. The approach features a rapidly spinning liquid film as the calorimetric medium, and as such can accommodate a wide spectrum of incident laser radiation, through appropriate selection of the absorbing fluid. Because of the rapidly moving thin fluid technique utilized in the construction, the calorimeter exhibits fast response, even at high or low power levels. The design concept and method of fabrication make the device quite rugged and virtually burn-out proof.
