Measuring Very Low Power IR Lasers with the RM9 Radiometer System
There are two main technologies commonly used today for measuring laser beam powers: Photodiode-based sensors, used for measuring low powers (from pW up to several hundred mW, typically); these are limited to spectral regions from the UV to the near IR, depending on the specific semiconductor used, and Thermal sensors, used for measuring higher powers;…

A Shortcut for Calculating Laser Power Density
This post was originally posted in 2012. It is still very popular, so I wanted to share it here in case you get some value from it. Here’s a laser power density calculator, if that’s what you wanted. Laser engineers and technicians are often required to calculate a laser’s power density to determine whether a beam…

Optical Alignment: A Simple Solution to an Infuriating Problem
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?

Non-Contact Beam Profiling of 100 kW and Above: How Can This Work?
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?
