Paper Abstract

A new kind of absolute absorbing high-power laser energy meter is reported in this paper. The energy meter has the advantage of simpleness, high damage threshold and high precision. The measurement principle, material and the structure of the energy meter is introduced in the paper. Many different kinds of effectors affect the high-power laser energy measurement results, these factors including backscatter, heat loss and accuracy of temperature measurement etc. The paper analyzes all these effectors on the measurement results and the consponding compensating models is given to enhance the measurement results. Energy meter measurement uncertainty is given in the end.
