Lasers are famous for their focusability. (As in: “laser-focus.”)

That’s why many laser power sensors have 30, 20, or even just 10 mm apertures. This is usually more than enough space for a laser beam.

But what about large lasers like diode stacks or non-laser light sources? How can a small sensor measure a large laser beam?


Modern production facilities must constantly increase throughput, at less cost, with less scrap, and with minimum downtime. In this video overview, you will learn how application of new, advanced technology in measurement devices, can help both designers and users of industrial laser systems to optimize and control their processes, so they can accomplish these goals and achieve consistently good results – both in quality and quantity.

Focus shift monitoring of high power lasers


Measuring the focal spot of a high power laser is challenging, at best.

The main issue is that when a high power laser is focused down to a small point, the power density can be extremely high, typically high enough to damage any sort of measurement equipment you would use.

The solution?


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.


With high power lasers, there’s always a safety concern for equipment and people nearby.

(Of course, I’m not qualified to give a detailed analysis of what needs to be taken into account for laser safety. For that, you should consult a laser safety officer.)

I want to specifically ask whether there’s an issue of laser light reflecting off power measuring equipment.
