Non-Contact Beam Profiling of 100 kW and Above: How Can This Work?
I’ve mentioned BeamWatch before.
It’s an innovative technique for profiling high power lasers (1 kW and up).
I’ve even touched on the underlying Rayleigh scattering effect that makes this possible.
But how does this really work?

How Stray Light Affects Laser Beam Profiling
CCD camera beam profilers are very sensitive to light.
So what happens when we consider ambient light? How about other light sources in the area, such as laser pumps?
There are two issues that can be caused by unwanted light getting into the camera:

Must You Measure Industrial Laser Performance?
With all the advancements in laser technology, lasers have become higher quality and more consistent.
Laser manufacturers test and measure their lasers during development, to make sure you, the laser end user, get the highest quality laser system.
With all this in mind then, do you really have to measure your laser system?
