How to measure laser power?

1. Use bigger sensor expose area so that all your laser beam fits into the sensor surface. 2. Use a lens to focus on to the sensor (whatever you have). You will be measuring the same laser power. However with second solution, you have to take into account lens losses Join ResearchGate to ask questions, get input, and advance your work.

What is a laser measurement system?

Laser measurement system is also used to measure flatness of surface plates. I work for a calibration company. We use a laser based system made by Optodyne, in Compton, CA.
