The Difficulties in M-Squared Measurement –And How to Overcome Them

A clear benefit of knowing the M2 of your laser is getting a lot of information about beam quality all in one number.

As simple as the output is, it is harder than you may imagine to measure and calculate M-Squared.

Let’s take a quick look at the theory behind M2 to see how it can be measured.

How to Keep a Laser Power Sensor Clean




These are a few words used to describe an industrial environment.

What about your laser sensor? Will it survive this?

Improve Your Laser Marking Process

Lasers are amazing. They can cut or weld, drill or solder.  A very general application of laser materials processing is called laser marking.  This can refer to a host of processes, like:  etching, engraving, ablating, etc. Here’s a question I never considered: How can you be sure that your laser will mark the wood (or…

Peak power vs. Average Power What is it, and how do I measure it?

A pulsed laser could have an average power of, say, 1 Watt, yet a peak power of 1 Megawatt – so when specifying it’s rather important to understand the difference! Contact us

M-Squared: Lasers’ KPI (Key Performance Indicator)

  With all of today’s technology, we are drowning in data. I know this is true in fields like marketing and running a business, and I’m sure it rings true with measuring your laser as well.  There are all sorts of things you can measure, but it’s never worth measuring something unless you plan on…

There’s No Wrong Way to Use a BeamTrack Sensor

Unlike a traditional thermal sensor which is basically just used for power, the BeamTrack sensor can measure several different aspects of your laser. We also call them power/position/size sensors, since those are the three fundamental functions of a BeamTrack sensor.  But it doesn’t have to stop there. Yes, if you need to measure your beam…

How to Find the Perfect Laser Beam Profiler

I wish I could tell you that there is one super-profiler, and it will profile any laser with 100% accuracy! Of course that’s a pipe dream. There are tons of different laser types, so it stands to reason that we’ll need several different profilers to cover the range of lasers.  There are cameras and scanning slit…
