Nippon Electric Glass (NEG) has developed advanced magneto-optical glass for high-power laser isolators. FM-02 offers a Verdet constant 1.7× higher than TGG, enabling compact isolators. For large-scale applications like laser fusion, NEG’s FM-03 achieves sizes up to 110×110 mm, delivering superior depolarization performance over TGG. These breakthroughs overcome crystal limitations and set a new standard for next-generation laser systems.
