Background noise subtraction: A crucial step in laser profile and power measurement
In this workshop, we will demonstrate the importance of subtracting background noise when making measurements of either laser beam profile or laser power. Background noise subtraction will be demonstrated for two different types of measurements: beam diameter measurement and laser power measurement.
In the first part of the workshop, we will measure the diameter of a laser beam with a beam profiler connected to a PC. We will show that noise from ambient light adds an error to the beam diameter measurements, which is removed with a background subtraction.
In the second part of this workshop, we will demonstrate how to reduce thermal drift and offset errors with a laser power meter. This demonstration will be presented with two types of power meters: a PC-connected detector and a wireless laser power detector connected to an iPhone.
