Beam quality analysis
Aug 2007Thorlabs Inc.Request Info
Thorlabs Inc. has introduced the BP1M2 series, an extension set for the BP100 series beam profiler that enables automated measurement of the M2 factor, a more accurate expression of beam quality than a single profile measurement. The set comprises a motor translation stage and mounting accessories. Stage movement is controlled by the beam profiler software, allowing measurement of the beam diameter at various positions along the propagation axis. A hyperbolic curve fit to the data yields values for the beam waist, diameter and position, as well as the Rayleigh range, divergence angle, beam pointing direction, waist and divergence asymmetry, and astigmatism.
