Abstract

A detection system of energy fluctuation has been designed using C8051F120 mirco-controller chip as the central processor. The detection system is based on the principle that the current output increases linearly with the growth of the input laser power under the condition of adding anti-biased voltage into PIN photo diode. Real-time monitoring output fluctuation has been achieved by measuring the output voltage of optical-electrical conversion which is related to the peak output of nanosecond laser.
