摘要:
An essentially non-intrusive laser power meter is described which is dependent on the reflection of a minor fraction of energy from a laser beam. A small beam splitter positioned on the periphery of the laser beam directs a small amount of the beam's reflected energy to a silicon photodiode. The output signal from the photodiode is then sent to a meter readout to indicate the beam energy.
