A Shortcut for Calculating Laser Power Density

This post was originally posted in 2012.  It is still very popular, so I wanted to share it here in case you get some value from it. Here’s a laser power density calculator, if that’s what you wanted. Laser engineers and technicians are often required to calculate a laser’s power density to determine whether a beam…

What’s M-Squared, again?

Here’s a surprising statistic: Nine out of ten laser technicians have no idea what M² is. Most laser beam characteristics are easy to put your finger on:  laser beam width, position and divergence angle are generally known to those that work with lasers – and if not, can be learned quickly.

Can a Simple Sensor Really Replace a Laser Beam Profiler?

So you need to profile your laser beam but are worried about the cost of a beam profiler? Or maybe you just think it will be too complex for your technicians? BeamTrack is a laser power sensor that also measures beam size (PPS version only) and position (all versions). My question: Can you use BeamTrack…
