Laser power precise measurement using calorimetric method
Abstract
A new double calorimeter designed in order to establish the continuous-wave laser power mesurement standard is described. The double calorimeter consists of a standard thermopile unit with fast response and an electronic cooling calorimeter whose thermal load is borne by the thermopile unit. The characteristics of the two units are studied in detail. Various errors related to determining the effective efficiency are theoretically and experimentally evaluated.
