BeamSquared® – Measurement of Long Rayleigh Range Lasers with Small Focal Spot

The development of remote material processing techniques requires increasing the accuracy of the process to permit creating smaller features. Laser systems, used for various industrial applications like material processing and micromachining, require small focal spots and at the same time, greater focal lengths. Small focal spots and greater focal lengths at the same time To…

Lab Story: Laser Measurement System for Stability and Quality

The R&D lab of a large jet engine manufacturer uses a laser welding cell in order to test and develop new laser processes. They needed a solution to ensure the laser remained stable and of the best possible quality. Their lab has two main lasers, both in the near-IR (1 μm). One is a multimode…

Overcoming the Challenges of Measuring High Power NIR Lasers

High power laser applications High power laser application has significantly increased in recent years due to new production techniques that enable cheaper manufacturing and operating costs.  Applications of high-power lasers that seemed exotic a few years ago are now considered routine in material processing and micromachining. Such material processing applications as welding, cutting, additive manufacturing,…

A Beginner’s Guide to Laser Beam Profiling

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.

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

Focusing a Gaussian Laser Beam:Which Formula to Use?

When focusing a laser, or anything for that matter, there’s a handy formula that is used to calculate the focus size and position.

It is generally called the thin lens formula, and it looks like this:
