A digital wavefront sensor for laser beam profiling has been released by PhaseView. Without special hardware, the instrument measures both beam intensity and wavefront in every pixel with high resolution. Real-time measurements can be used to compute the beam’s waist, exact focal plane, propagation factor and divergence. The company also offers three analog sensors: Shack-Hartmann, lateral shearing interferometry and curvature. Applications include laser welding, focusing and free-space communications.
