Can You Really Measure Laser Beam Quality (M Squared) in Real Time?
M-Squared is arguably the most important factor when determining the potential efficiency of your laser.
But, it can be a pain to measure. Here are 2 ways you can use that actually DON’T move the camera or the laser

Measuring Really Small Laser Beams (< 10 microns)
Profiling small laser beams and measuring the beam size (or mode field diameter) can be a serious challenge. But it’s critical to measure, especially in such applications as fiber optic coupling efficiency, defect scanning, optical design and optical fabrication process control. Here’s how we suggest you do it

How to Calculate Laser Beam Size
Gaussian laser beams don’t have a clear‑cut width. This article explains how laser beam size is calculated using common definitions such as 1/e², FWHM, and D4σ.

Using a Silicon Beam Profiler for UV Lasers?
Read this before before you do any damage.
Technically, silicon absorbs well down to 350 nm, and could even work at lower wavelengths (to 190 nm).
However,
