Two-mirror beam shaper
WebA beam shaping concept with two deformable mirrors is investigated in order to provide automated optimization of the laser quality for astronom-ical AO. This study aims at demonstrating the correction of quasi-static aberrations of the laser, in both amplitude and phase, testing a prototype of this two-deformable mirror concept on GeMS. WebWe have developed a two-mirrors beam shaper in o rder to improve the spatial overlapping between the pumping and the signal beam in a dye laser amplifier transversally pumped b …

WebTwo-mirror beam shaping of a 94% fill-factor laser diode bar was investigated. We show that optimal output for the purposes of end pumping was achieved by configuring the … Webshaping of the laser beam profile used to illuminate the photosensitive resin. Suppose all the micro-mirrors in DMD chip are turned on and they are all situated on the “on” state. The input laser beam reflected from DMD will pass through the pinhole which acts as a spatial-frequency low pass filter in the back focal plane of L2.
