Laser Beam Quality, M² Measurement, Visible Low Divergence

Numéro de référence fabricant :


Fabricant Coherent


Description :

The ModeMaster MM-2 Si beam profiler measure the laser beam quality M² factor and beam propogation. The ModeMaster MM-2 model PC head is a dual-knife-edge Si beam profiler (340nm to 110nm) integrated with a diffraction-limited precision scanning lens, which is translated along the beam propagation axis. The visible low divergence lens focuses the beam to create an internal beam waist, and the two orthogonal knife edges (X and Y), which are mounted on a rotating drum, measure the beam diameter and beam axis location at 256 planes along the beam waist as the lens is translated. The powerful ModeMaster PC software then derives the M2 factor, the size and location of the beam waist, the far-field divergence angle, the pointing direction, astigmatism and asymmetry, and the Rayleigh range.
