How to Measure High Power Laser Beams. Really High.

Usually, deciding how to measure your laser is a task of sifting through the various providers to find the laser power meter that best fits your needs.  For some lasers, however, the difficulty is not in choosing a power meter, but in finding one at all.

High power lasers are a perfect example.  Up to 10kW there are generally still several options, depending on your other parameters of course. (Such as wavelength, pulsed vs. CW, desired accuracy, etc. )  In excess of that, however, it becomes exceedingly difficult to find any laser power sensor.

Ophir is a heartfelt believer in the continued expansion of laser applications and lasers themselves.  But we know how important it is to measure your laser in order to use it to its fullest potential.  So we really feel it is our duty to the laser industry to provide quality laser measurement instruments for all sorts of lasers.  If you need to use Laser X for your application, we’d like to be sure we can help you control it.

That’s why Ophir is so excited by its latest power sensor, the 30K-W-V1-74.  (Let’s call it 30KW for short.)  Not only can this sensor measure lasers all the way up to 30kW (as I’m sure you’ve guessed by now), but it can also measure down to 100W, giving it a dynamic range of 300:1.

The 30KW Laser Power Senosr

If you’re an experienced high power laser user, you may be saying to yourself at this point, “Okay, so you say you can measure 30kW power, but what about power density? 30kW is impressive, but it’s only helpful for me at a reasonable beam size.”  This is an important consideration, and one that could be easily overlooked – but don’t worry, the 30KW is good up to 10kW/cm2 so even at the maximum 30kW the laser beam size can be as small as 3cm2.

I could go on and on about the 30KW and all its wonderful features, but I’m sure you’re busy, so let me just tell you that this sensor can measure the highest power of any commercial laser power meter, and you can always contact us for more information.

Find out more about the 30KW sensor.

One last thing.  Do you know someone that might be interested in finding out about high power laser measurement capabilities?  Why not share this with them?
