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?

Focusing a Gaussian Laser Beam:Which Formula to Use?
When focusing a laser, or anything for that matter, there’s a handy formula that is used to calculate the focus size and position.
It is generally called the thin lens formula, and it looks like this:
