Is your laser’s focus spot where you think it is? This video shows the focal shift of a 100 kW laser during the first four seconds of startup using BeamWatch, Ophir-Spiricon’s non-contact high power beam analyzer.

Sometimes a laser is used in a “pass-through” setup, which begs the question: What happens to the laser after it passes through?
Consider for example a sensitive camera that is used to profile a laser. Beam splitters are often used to deflect only a small percent of the laser intensity into the camera. The other 90% or more passes straight through the splitter.

We talk a lot here about lasers.
How to measure laser power, energy, size, and distribution profile. How to avoid damage from lasers. Etc., etc.
But what about other light sources?

Glad you asked.
Like many answers to many questions, the answer here is “sometimes yes, sometimes no.”
To explain this, we must look at each of the three main types of laser power/energy sensors:

In order to measure your laser, you need two things:
Thing One: A sensor, to convert photonic power into an electrical signal.
Thing Two: A meter, to measure the electrical signal, digitize it, and display the results.

Some people prefer to use a PC to display their laser measurements. Some use a power meter.
But if you are a service technician and find yourself lugging equipment from one site to the next, this might be your saving grace.
Ophir recently released an Android app called StarViewer.

Picture this:
You’re working on a complicated laser setup, with various beam splitters, attenuation, lenses and mirrors. You spend weeks optimizing the design, and months waiting for all the parts to arrive.
Now everything is here and you set it up to the millimeter.
And then the big moment. Where’s the laser?

You need a sensor (thermal, photodiode, pyroelectric) to measure laser power, but how do you take that raw measurement signal and move it to a display. You have a few options, and in this post will explore the benefits of Juno – as well as the cases when other options would be preferred.

You might think – as I used do – that offset is pretty simple.
Before measuring your laser, see if the meter displays a value.
If not, great. If it does, that’s unwanted, so press “Offset.”
However, the truth is there are several different kinds of offset and it’s important to understand a little bit about how thermal sensors work in order to know when to hit that offset button and when to resist.
