Abstract

ADLINK PCI-9114 multifunction data acquisition card, signal amplifier and multiplexer board and power sensor are used to establish the real-time measurement system of relative laser power. During producing laser, measuring and showing thermoelectric and photoelectric signal, calculating parameter and drawing the curve of relative power. Parameters of laser output power and energy are concerned with researchers. These parameters are important for evaluating laser system. In this paper, a real time laser power measure system is established. While laser system is operating, real time laser power measure system measured the power and energy of laser and plotted the waveform of relative laser power. The parameters such as pulse width, rise time, fall time, power integration, average power, peak power and average energy are computed.
