WebMultikilowatt fiber and disk lasers used for assembling fuel cells and for welding battery components can now be monitored by noncontact beam profiling systems. These integrated systems find the focal plane — the location along the propagation axis of the smallest spot size — and, based on the total power in the beam, derive an irradiance ... WebThe monoscanning system performs illumination and detection simultaneously through each rotating aperture on the disk, maintaining the coincidence that the two light paths exhibit while passing through the …
