A Beginner’s Guide to Laser Beam Profiling
Let’s be honest. We’d all just prefer that our lasers always worked exactly as they’re supposed to. Who really wants to measure their laser, when they can just be using it instead? However, like all processes, a laser must be controlled to be used efficiently, and it must be measured to be controlled (and used) properly.
What is a Tube Laser?
Tube lasers are starting to come online now with regularity. These are very big, very complex and very expensive machines—hence they have not hit the manufacturing market with the same force tradition flat sheet lasers did in the past. So, what is a tube laser? Tube Lasers are setup to laser cut ...
How can I use a laser projector for a longer life?
The use of laser projectors in theaters has become more and more popular, which is mainly due to the long life of the laser light source and the stable brightness maintenance ability.

4 emerging trends in the Laser technology
4 emerging trends in the Laser technology. Smart dishwashers and washing machines have been installed with sensors that use laser technology.
How Lasers Can Spot a Dirty Bomb in a Cargo Container
Nuclear materials cannot hide from this instrument.
How to Keep Your Industrial Laser Process Running Smoothly
And anything made of matter will degrade with time. It consists of two parts: power (W) and beam size (cm2). Each of these can be measured – and should be, to make sure your laser is still acting like it did when the process was developed and when it worked properly<br>You can measure the power with a laser power meter and the beam size with a beam profiler .<br>As you can see from this simple diagram, each stage of the laser…
How to Increase Laser Welding Efficiency and Reduce Scrap
Your laser welding system is not producing the quality welds you expected<br>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.<br>But measuring focus spot is easier said than done<br>It’s isn’t your fault, though. No beam profiler can measure such high power laser beams – at least not at the focus spot.<br>However, if you can’t measure your focus spot size and…
What to Do when Your Laser Doesn't Perform to Spec
You’re so upset you could spit<br>You just got a new laser for your factory floor, but it just won’t make parts that pass inspection<br>After investing time and money to purchase and set up the top-of-the-line laser system, now you have to stop the whole production line to figure out what’s wrong.<br>Sound familiar?<br>About Blog<br>Ophir’s Photonics group manufactures, calibrates and sells a complete…
The Navy Is Using Lasers to Find Cracked Parts Before They Fail
The system can use light beams detect critical damage before it even happens.
How to Profile Large, Small, and High Power Laser Beams
I know I do<br>Problem is that the very thing that makes a beam profiler so perfect for one laser renders it useless for a different laser.<br>At risk of overcomplicating matters, we like to provide our customers with maximum flexibility. So you can get one laser beam profiler and use it with many different kinds of laser beams – you’ll just need the proper accessories to use with each laser.<br>There are two main issues that will come up: laser intensity and…
How to Center Your Laser Beam for More Accurate Power Measurement
There are several considerations when you’re trying to maximize laser power meter accuracy<br>One that I don’t usually mention is perhaps the most obvious question: How do you know the entire laser beam is actually hitting your sensor?<br>I mean, if you have a visible laser, fine. But most lasers these days are in the near infrared region. Many sensors, especially in the low power region (~10 W and below) have small apertures .<br>It may look like your laser and sensor are…
What laser optics designers need to know about high-LIDT optics fabrication
Techniques used before, during, and after optical fabrication ensure consistently high laser-induced damage thresholds for custom reflective, transmissive, and absorbing laser optics.
