Measuring Profiles of Non-Laser Light Sources
We talk a lot here about lasers.
How to measure laser power, energy, size, and distribution profile. How to avoid damage from lasers. Etc., etc.
But what about other light sources?

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:

Q&A: M-Squared Laser Beam Quality
What’s M-Squared, again?
If you’re not familiar with M2 already, it basically sums up your laser beam quality in a single number.
M2 takes a look at your beam caustic (the curve of the laser beam as it focuses and diverges again) and compares this to an ideal Gaussian beam caustic.
So if your beam is perfectly Gaussian, you’ll get M2 = 1. For high quality beams, M2 might be 1.1 or 1.2, for lower qualities you can get up to 3, 4 and even double digits for some low quality high power lasers.
So, how do you know what the M2 of your laser beam really is?

What to Do when Your Laser Doesn’t Perform to Spec
You’re so upset you could spit.
You just got a new laser for your factory floor, but it just won’t make parts that pass inspection.
