Measuring Really Small Laser Beams (< 10 microns)

Profiling small laser beams and measuring the beam size (or mode field diameter) can be a serious challenge. But it’s critical to measure, especially in such applications as fiber optic coupling efficiency, defect scanning, optical design and optical fabrication process control. Here’s how we suggest you do it

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…

A Quick Guide to Profiling Small Laser Beams

When using a camera to profile your laser, it’s important to keep the ratio of laser size / pixel size higher than 20. Not only does this increase the resolution of your profile image, but it also makes your measurements more accurate. (If you have fewer than 20 pixels in your beam, the measurement accuracy…

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.

How to Profile an Ultraviolet Excimer Laser

Ultraviolet excimer lasers are important for many applications: primarily medical and photolithography, but not exclusively.  Measuring them, however, is not always so simple. We recently encountered a company that needed to know how evenly their excimer laser beam was distributed in space.  They tried imaging their beam with specialized ultraviolet cameras, but all they got…

How to Profile Very Short Pulsed Laser Beams

A laser beam profiler is more or less a specialized camera rigged to measure beam width, divergence, and other qualities of the laser’s spatial intensity distribution. So, like any camera, it has a trigger which takes a given amount of time to open the shutter. Let’s say for argument’s sake that it take only 10μs…
