41. Signal-To-Noise Ratio vs Calibration Uncertainty vs Repeatability In Laser Power And Energy Measurement 7/6/2020

    It is common to search for the measurement solution with the lowest uncertainty of measurement for laser processes involved in demanding applications such as medical device manufacturing or aerospace parts manufacturing, where traceability is key to a production line. Calibration uncertainty of a laser power meter or energy meter may not be the only specification needed checked. Repeatability, linearity and noise equivalent power or energy are other specifications that must be checked out as well. Let’s make it simple! This article will help you select the right detector for your laser measurement needs and quickly.

42. How To Measure Laser Power Accurately In 7 Simple Steps

    How do you get the most accurate measurements possible from your laser power meter? Are there simple step-by-step instructions on how to make a power measurement the same way a laser expert would? Yes! This article offers a guide on how to measure laser power accurately using a Gentec-EO thermal laser power meter.

43. The Beginner's Guide To Laser Beam Quality And M2 Measurement

    A pure Gaussian beam with a TEM₀₀ profile and a bell-shaped curve that spreads on infinitely is never achieved. This guide introduces the concept of laser beam quality measurement with the M2 parameter, which quantifies the laser beam quality, and how to measure M2 for a real laser.

44. How To Ensure Laser Power Stability In Your Processes

    This article will cover the recurring concept of laser power stability, which is critical to better understand when you want to optimize your current or future setup involving Gentec-EO detectors.
