How To Remove Background Noise For Accurate Laser Beam Profiling And Power Measurement

In laser beam technology, ‘noise’ describes any background interference, which may cause fluctuations in a beam’s measurements. This noise, which typically comes in the form of stray ambient light, can affect both beam diameter and power measurements. In most cases, these erroneous readings are larger than they are supposed to be. This article outlines how to minimize background noise and improve the accuracy of readings when performing both diameter and power measurements.
