Lasers: IO wavefront sensors are up to the task A tool designed for the specific needs of laser users and manufacturers
Lasers, used for many applications in scientific and industrial fields, are distinguished from other light sources by their coherence. Spatial coherence is typically expressed through the output being a narrow beam, which is diffraction-limited. Laser beams can be focused on tiny spots, thereby achieving a high irradiance, or they can have low divergence in order to concentrate their power at a great distance. Many instruments have been developed to tune and characterize laser systems, but Shack-Hartmann wavefront sensors are among the most versatile of these. Indeed, Imagine Optic’s wavefront sensors characterize not only the laser beam’s intensity and phase but also its divergence, PSF, beam’s waist diameter and M2 parameter, all in a single measurement. The combination of these sensors with the ILAO Star deformable mirrors and WaveTune software offers the ideal adaptive optics solution for achieving the ultimate focusing of ultra-fast or ultra-high intense lasers.
