Beam Profiling 101: Intro to laser measurement

One of the most common questions Mark S. Szorik, Pacific Northwest Regional Sales Manager at Ophir Photonics is being asked, is “Why do I need a beam profiler and what tools and methods do I need to profile my beam?”

Reducing Production Waste with Laser Profiling and Characterization

A laser profiling system can characterize and identify which variables affect product quality and waste.
But many laser users have never evaluated the quality of the beam beyond the initial delivery. This leads to frequent process adjustments to try to get back to “normal” and frantic calls to outside laser services.

Can a Simple Sensor Really Replace a Laser Beam Profiler?

So you need to profile your laser beam but are worried about the cost of a beam profiler? Or maybe you just think it will be too complex for your technicians?
BeamTrack is a laser power sensor that also measures beam size (PPS version only) and position (all versions).
My question: Can you use BeamTrack as an alternative to a full laser beam profiler?

Sort of.

It really depends on what you need to measure.

Product Focus: Using Ophir’S BC20 to Evaluate Scanned Effects in Light Show Applications

Music concerts, along with other entertainment venues such as nightclubs and theme parks, use laser sources to create colorful and vivid lighting effects.

Even with advances in non-coherent lighting, technology has not been able to replicate the unique appearance of laser lighting effects.

The types of lasers used for light show applications typically emit radiant powers in excess of 20W over a range of common wavelengths based on the technology employed in the projection device. Devices emitting such powers place them firmly into Class 4 laser product territory. How do laser officers deal with the challenge and what does Ophir have to offer? Coming up…

Technical Tip: How to select a power and energy meter – part 2

So, as we’ve started discussing the best way to pick a power meter last week, we’ve reached the third piece of data we need – and that is the laser wavelength. Why is it so important? In order to match it to the sensor absorber characteristics.

We need to select a sensor whose wavelength is within the measurement range of the sensor, power rating is equal to or higher than the maximum power we will measure, whose aperture is larger than the laser beam diameter so that it will contain the whole beam, and whose damage threshold is higher than the maximum expected laser power density at the given wavelength. The sensor absorber should be selected so it matches the wavelength for higher absorption.
