Is Your CO2 Laser Cutting Slowly?

It might be time to measure your laser power. Laser cutting speed is a function of the material type, thickness, and laser power. So as your laser degrades, it’s natural to find it performing slowly. Read more in this firsthand account, from Derrick Peterman, our Northern California Sales Engineer: Ensuring High Cutting Speeds Through Accurate…

Measuring Really Small Laser Beams (< 10 microns)

Profiling small laser beams and measuring the beam size (or mode field diameter) can be a serious challenge. But it’s critical to measure, especially in such applications as fiber optic coupling efficiency, defect scanning, optical design and optical fabrication process control. Here’s how we suggest you do it

How to Center Your Laser Beam for More Accurate Power Measurement

There are several considerations when you’re trying to maximize laser power meter accuracy. One that I don’t usually mention is perhaps the most obvious question: How do you know the entire laser beam is actually hitting your sensor? I mean, if you have a visible laser, fine.  But most lasers these days are in the…

Worried about High Power (10 kW) Laser Backscatter?

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.

What to Do when Your Laser Doesn’t Perform to Spec

You’re so upset you could spit.

You just got a new laser for your factory floor, but it just won’t make parts that pass inspection.

Photometric Measurements: Measuring Illuminance with the PD300-CIE

In applications where a human observer is involved (for example illumination applications), it is often important to measure using the eye-response-matched Photometric system of units. Ophir’s PD300-CIE is a photometric sensor, and is designed to measure illuminance (in units of Lux or Foot-Candles).

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

Harsh.

Extreme.

Noisy.

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…
