Fiber laser beam quality
WebMay 20, 2011 · There are limits to the core diameter in a fiber laser before the beam quality degrades and the guidance becomes too weak, which causes problems with bend loss and packaging. This occurs in the 50- to 100-µm region, although the cores in commerical single-mode devices are seldom larger than 30 µm. WebThe M2 factor of a laser beam limits the degree to which the beam can be focused for a given beam divergence angle, which is often limited by the numerical aperture of the …
