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.

Updated March 2016: I made a few changes to this post now that the new low power RM9-PD is available.
There are many different types of lasers.[citation needed]
UV, visible, infrared, Terahertz.
Nanowatts, milliwatts, kilowatts.
Lasers for industry, laser for medicine, lasers for telecommunication.

The 3A family of laser power sensors is one of our most popular – and for good reason.
You might already know the basic points:
It’s very sensitive (down to 10 μW), yet comes with all the benefits of a thermal-based sensor: high damage threshold and spectrally flat across a very wide spectral range.

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?

Broadband spectral sources, such as arc lamps or gas-discharge lamps are still used in many lighting applications due to their high efficiency and other unique characteristics.
Lasers are measured with laser power meters. But how can you measure a broadband spectral light source?

Pyroelectric sensors are the tool of choice for measuring energy of repetitively pulsed laser beams.
They measure energy, and they’re fast.
They are not, however, indestructible.

I’ve mentioned BeamWatch before.
It’s an innovative technique for profiling high power lasers (1 kW and up).
I’ve even touched on the underlying Rayleigh scattering effect that makes this possible.
But how does this really work?

Disclaimer: Don’t do anything stupid.
What I’m about to tell you is a trick that should NOT be used lightly.
However, in many cases Ophir sensors can be used for far higher powers than in the spec, as long as it’s only for a short time exposure.
