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.
For every wavelength of laser along the electromagnetic spectrum, Ophir-Spiricon can measure the output. This video briefly introduces the equipment used in the different regions of the spectrum to measure and profile lasers.
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?
