At Wasatch Photonics, we’ve built a team that understands the needs of OEM customers, and a spectrometer bench that exceeds them. Our OEM spectrometer modules are robust, compact, and easy to integrate, while delivering the same outstanding sensitivity and SNR of our laboratory products.
How to ensure laser power stability in your processes Laser stability is an idea that tends to be associated more with continuous wave (CW) lasers.
This article will therefore refer more to lasers of this type in particular, but most points discussed below also apply to pulsed lasers as well. Concepts specific to pulsed laser applications are gathered in the last section of this article.
Signal-to-noise ratio vs calibration uncertainty vs repeatability in laser power & energy measurement
It is common to search for the measurement solution with the lowest uncertainty of measurement (i.e. the highest accuracy, if you will) for laser processes involved in demanding applications such as medical device manufacturing or aerospace parts manufacturing, where traceability is key to a production line.
