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…

Tech tip: Measuring Power Out of a Fiber

There are many applications that involve measuring power out of a fiber, where the power is in the range of tens of µW to a few mW. A customer recently found that every time he disconnected the Fiber Optics connector from the adapter and then reconnected, the power read 50-100 µW higher.

Laser Monitoring in Your Factory Line – with Profinet

“You can do Profinet, right?”

John had just ordered 10 laser welding stations for his new car manufacturing facility. As a laser system integrator, you talked to him in detail about all the specs. What exactly does he need from the laser? What sort of control equipment does he have? What else does he need?

John added, almost as an afterthought – “The facility is in Germany, so of course we want all the lasers and devices running on Profinet. You can do that, right?”

Uh-oh.

Non-Contact Beam Profiling of 100 kW and Above: How Can This Work?

I’ve mentioned BeamWatch before.

It’s an innovative technique for profiling high power lasers (1 kW and up).

I’ve even touched on the underlying Rayleigh scattering effect that makes this possible.

But how does this really work?

Must You Measure Industrial Laser Performance?

With all the advancements in laser technology, lasers have become higher quality and more consistent.

Laser manufacturers test and measure their lasers during development, to make sure you, the laser end user, get the highest quality laser system.

With all this in mind then, do you really have to measure your laser system?

How to Measure Optical Fiber Power and Energy

Not everyone knows this, but almost all Ophir power and energy sensors can be used with four standard fiber adapters:

SMA
FC
ST
SC
Of course, any fiber can be measured by an Ophir sensor by taking a free-space measurement – placing the fiber tip a few mm or cm from the sensor and letting the laser beam continue to the sensor.

However, in many cases it is convenient to use a fiber adapter to connect to a measuring device.

If that’s the case, here’s what you’ll want to do.
