Finding the right sensor to measure your laser pulse energy can be daunting. It doesn’t help that measuring energy tends to be more complicated than measuring power. There are more parameters that need to be considered and this leads to more lines in the datasheet for each energy sensor. In this slideshow, I explain what…
The new StarLite power/energy meter is an economical instrument that supports all our newest lines of standard sensors. This video shows you how easy it is to use.
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…
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.
Whether your laser beam is too small or too large, you need to add some optics (an expander or reducer). But there are two fundamentally different types: reimaging and Galilean telescope optics. Which one is right? Depends on your application. But before I explain when to use each type, let’s take a look inside these…
If all your laser measurement work involves a laptop or a PC, rather than a stand-alone meter, one of Ophir’s direct-to-PC interfaces could be an ideal solution. These are full-fledged Laser Power and Energy meters, but instead of having a separate on-board display, the PC becomes your display. In this video you will learn about…
Pulsed lasers are complicated. When you’re dealing with a CW (continuous wave) laser, things are nice and simple. The laser light has a certain power, and that’s exactly what you’re measuring with your laser power meter. But a pulsed laser is much more complex. Besides power, you also need to worry about pulse energy,…
This is a great one. It’s one of those head-smackingly simple ideas that make you say, “Why didn’t I think of that?” A Little Trick Goes a Long Way Here’s how to turn an everyday power meter into a laser power density meter:
ND filters are a great way to get your laser down to a manageable power for beam profiling. But what’s the best way to physically attach the filters to your laser beam profiler?
