Terahertz Technology- New Challenges, New Solutions

Terahertz (=THz) radiation is electromagnetic radiation located between the low-frequency far-infrared and the high-frequency microwave parts of the spectrum (from 0.3 to 3 x 1012 Hz, with a wavelength from 10 micrometers to 1 mm). THz radiation is unique because it combines useful properties of both radio waves and infrared waves. THz radiation can be…

A Shortcut for Calculating Laser Power Density

This post was originally posted in 2012.  It is still very popular, so I wanted to share it here in case you get some value from it. Here’s a laser power density calculator, if that’s what you wanted. Laser engineers and technicians are often required to calculate a laser’s power density to determine whether a beam…

Don’t Come to Our LASER World of PHOTONICS Booth Unless…

Going to Munich for LASER World of PHOTONICS 2015?

We’ll be showing several new products in Munich, not to mention quite a few of our classics.

But…

You’re going to be busy. You can’t (and shouldn’t) go to every booth. So I’m going to very clear. Our booth is not for everyone. However,

Worried about High Power (10 kW) Laser Backscatter?

With high power lasers, there’s always a safety concern for equipment and people nearby.

(Of course, I’m not qualified to give a detailed analysis of what needs to be taken into account for laser safety. For that, you should consult a laser safety officer.)

I want to specifically ask whether there’s an issue of laser light reflecting off power measuring equipment.

What to Do when Your Laser Doesn’t Perform to Spec

You’re so upset you could spit.

You just got a new laser for your factory floor, but it just won’t make parts that pass inspection.

The Difficulties in M-Squared Measurement –And How to Overcome Them

A clear benefit of knowing the M2 of your laser is getting a lot of information about beam quality all in one number.

As simple as the output is, it is harder than you may imagine to measure and calculate M-Squared.

Let’s take a quick look at the theory behind M2 to see how it can be measured.
