METHOD FOR FORMING ANTIREFLECTIVE LAYERS, OPTICAL ELEMENTS, IN PARTICULAR BARS FOR LASERS, HAVING AN ANTIREFLECTIVE LAYER AND LASER HAVING SUCH OPTICAL ELEMENTS

摘要

THE INVENTION CONCERNS THE FORMATION OF ANTI-REFLECTIVE LAYERS. It relates to a process for forming anti-reflective coatings on silicone glasses containing at least 5% by weight of alkali metals. THE TREATMENT INCLUDES AN ATTACK BY A NEUTRAL OR SLIGHTLY ALKALINE SOLUTION, IN THE PRESENCE OF IONS OF A MULTIPURPOSE METAL. THE PRIMORDIAL PARAMETER FOR OBTAINING REPRODUCIBLE ANTIREFLECTIVE SURFACE IS THE GLASS SURFACE RATIO TO BE TREATED AT THE VOLUME OF THE TREATMENT SOLUTION. / P P APPLICATION TO THE MANUFACTURE OF LASER AMPLIFICATION BARS. / P
