Abstract: An analyzer of the spatial intensity distribution of a laser beam focused or transmitted by an optical fiber comprises: a shaping lens; a device for taking a partial sample of the beam; a heat sink; a photodiode; an imaging lens to form images of the plane on an image sensor; a motorization of the shaping lens to translate along the optical axis; a motorization of the imaging lens to translate in a plane perpendicular to the optical axis; a motorization of the image sensor to translate along the optical axis; an electronic unit controlling each motorization; an electronic unit synchronizing the image sensor, connected to the photodiode to synchronize image capture with the laser pulses or in the pulses; an electronic unit adjusting the aperture and/or gain of the image sensor; and a software interface parameterizing and piloting the electronic control units, equipped with an image processing unit.
