How to measure laser beam quality
WebThe quality of the laser beam is largely determined by two factors: Wavelength Energy density (or power density) These factors are largely influenced by two separate factors, which can be managed as needed. Beam parameter product (BPP) Laser intensity Beam parameter product (BPP) WebMost of the time the measurement is made by placing the beam profiler at some distance from the laser source and aligning the beam until it points to the ideal target. For laser scanning applications the measurement may be made in different locations across the scan plane to ensure proper linearity of the scan.
