5.1 Measuring Principles
The absorber of the calorimetric measurement system is irradiated by a laser for a short
period of time. The temperature difference of the absorber between start and finish
of the laser pulse is measured. From the increase in temperature, the microprocessor
based electronics is able to calculate laser power to a high degree of accuracy.
