We describe several examples of technology transfer from academic laboratories to PHASICS. PHASICS was created in 2003 as a spin-off of LULI an academic laboratory working on plasma physics and developing high power lasers to create such objects which temperature and pressure conditions are close to those at the center of stars. In order to optimize the intensity at laser focus, several thesis treated the subject of adaptive optics for lasers. LULI decided to collaborate with ONERA who just invented a technique for wave front sensing called multiwave lateral shearing interferometry. Though developed at first for infrared metrology applications, this technique proved to be very efficient with lasers because it was able to analyze wave front of modulated beams with sharp edges. Before being industrialized the technique was further improved to a compact version called quadriwave lateral shearing interferometry. As soon as PHASICS was created, we felt the potential of making wave front images from transparent objects because of QWLSI high spatial resolution. PHASICS and Institut Fresnel started a collaboration to study applications in microscopy imaging. Research subjects include biological imaging, CARS microscopy, anisotropy imaging, or laser damage testing. The results of research were then included in PHASICS products but sometimes only a tool developed during the project became a product. We will present research works that led to transfers as well as the method we used to ensure fruitful collaboration and transfer.
