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…

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 Low Power Lasers (Picowatts to Watts)

There are a few different ways to measures laser power, but the most common is the photodiode. Photodiodes translate light energy into electricity (current), which can be measured by a current sensor.

Ophir uses a few types of photodiodes in its PD300 series.

Focus shift monitoring of high power lasers

Measuring the focal spot of a high power laser is challenging, at best.

The main issue is that when a high power laser is focused down to a small point, the power density can be extremely high, typically high enough to damage any sort of measurement equipment you would use.

The solution?
