High-quality fluorides laser crystals
High-quality fluorides laser crystals
MEGA Materials is an Innovative Startup and a spin-off of Pisa University, devoted to the growth of high-purity fluoride crystals, with application in solid-state lasers, optical cryo-coolers, metrology, energy, and communication.
We also provide additional services such as crystal orientation, cutting and polishing, and polarized UV-VIS-NIR spectroscopy (absorption, fluorescence, and fluorescence lifetime). Moreover, we offer a counseling service on the development of new materials, solid-state lasers, and optical systems.
We produce high-quality single crystals of fluorides via the Czochralski (CZ) tecnique. Our single-crystal boules have high omogeneity, excellent optical quality, and high purity.
Main products:
We produce high quality single crystal fibers of rare-earth-doped fluorides using the micro pulling down tecniques. This method allows to grow fibers with diameters unachievable with mechanical processing of larger boules.
Main products:
Our crystal can be doped with almost all trivalent rare-earth ions. Co-dopings are also possible.
