Lasers are made of matter – of stuff.
And anything made of matter will degrade with time.
So if the laser degradation and eventual failure is inevitable, what can be done?
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.
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
May 20, 2015 - by Mark Slutzki
FEATURED
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.
Harsh.
Extreme.
Noisy.
These are a few words used to describe an industrial environment.
What about your laser sensor? Will it survive this?
Lasers are amazing. They can cut or weld, drill or solder. A very general application of laser materials …
