Understanding Dynamic Range…The Numbers Game
There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this blog post is to explain some of the terminology used in the discussion of this parameter by both Ophir- Spiricon and other suppliers of beam profilers. Definition Dynamic Range is the ratio of the…

Watch: How to Measure Low Power, Slowly Pulsing Beams (“Low Frequency Power”)
Are you trying to measure a low-power, slowly pulsing beam (think of a VCSEL beam for example) – and getting frustrated? Measuring low-power, slowly pulsing beams using photodiode sensors can be surprisingly tricky. Learn about the technical challenges you’ll face when trying to measure such beams, and about the Ophir solutions that will help you.…

Evolution of Measurement Technology for Laser-Based Additive Manufacturing Systems
Ophir BeamPeek, integrated power measurement and beam profiling In laser powder bed fusion (LPBF) processes, metal powder is selectively melted layer by layer using a laser beam. With layer thicknesses of typically 30 to 120 µm, exact adherence to the predefined beam parameters is an essential prerequisite for ensuring that the structures generated exhibit the…

Detect Missed Pulses with Centauri External Triggering
If you are having problems with the performance of your pulsed laser and suspect that it might occasionally not be firing each and every pulse, then the Centauri power meter can help determine, and log, if and when there are indeed any ‘missed pulses’. Centauri can be configured to detect missed pulses when used together…

Destroy the Target, Not Everything Else: Beam Management in High-Power Directed Energy Laser Projects
Since Columbia University graduate student Gordon Gould and Bell Laboratories scientists Charles Townes and Arthur Schawlow (among others) coined the term LASER in the 1950’s, applications of the laser have seemed limitless. Working with these new discoveries had to be exciting, but applying hundreds of kilowatts of laser power, like the ones being used in…
