Polycrystalline material based on nanoscale spinel crystals activated by Co2+ ions.
Glass-crystal material for passive Q-factor modulation of lasers, which is not inferior in characteristics to passive gates based on expensive single crystals of alumomagnesium spinel. Durability in operation. High uniformity, high mechanical strength, stability of laser output power. The sizes are practically unlimited.
