Let’s be honest.
We’d all just prefer that our lasers always worked exactly as they’re supposed to.
Who really wants to measure their laser, when they can just be using it instead?
However, like all processes, a laser must be controlled to be used efficiently, and it must be measured to be controlled (and used) properly.
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
