The Focal Spot Size Calculator

There are matrix methods that can be used for propagating the diameter and curvature of the beam, but if your main interest is simply the location of the new focus (i.e. beam waist) or the size of the focal spot, you can use the Focal Spot Size Calculator tool on the Ophir website. Dr. Ivker Our expert – will explain you how

Laser Beam Optics: Calculating Focal Spot of a Gaussian Beam

Whether you’re in the lab or a job shop, you need your laser beam to be a specific size to do the job. Getting your laser beam to that size is not always simple. In fact, the more I learned about (and experimented with) lasers, the more I realized that there is no one simple…

Laser Beam Optics Calculators

A laser is a complicated animal. Whether you’re a lab researcher or an industrial worker, there are several parameters you might need to calculate, such as power density or ideal focus spot size. We’ve recently added a few calculators to our website. I hope these calculators make your work just a little bit easier. We…

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:

How to Find the Perfect Laser Beam Profiler

I wish I could tell you that there is one super-profiler, and it will profile any laser with 100% accuracy! Of course that’s a pipe dream. There are tons of different laser types, so it stands to reason that we’ll need several different profilers to cover the range of lasers.  There are cameras and scanning slit…

How to Profile Large, Small, and High Power Laser Beams

Don’t you wish there was a one size fits all beam profiler? I know I do. Problem is that the very thing that makes a beam profiler so perfect for one laser renders it useless for a different laser. At risk of overcomplicating matters, we like to provide our customers with maximum flexibility.  So you…

How to Increase Laser Welding Efficiency and Reduce Scrap

Stop me when this sounds familiar. Your laser welding system is not producing the quality welds you expected. You know what your laser’s power density should be and where the laser should be focused, but you never know what it actually is, or where it’s really focused. Contact us
