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.…

On-demand Webinar: High Power laser measurement challenges and solutions
Monitoring laser behavior in high-power applications is critical to keeping your process running properly. However, that monitoring – the laser measurement itself – is not trivial. There are many “little things” one could do that might unknowingly mess with the measurement, or even damage the instrument. For example: • At what point should the cooling…
