Description Co2+(Cobalt-doped magnesium aluminate spinel) crystals, commonly referred to as Co, are relatively new materials used in laser applications. These crystals are specifically designed for passive Q-switching in 1.2-1.6 μm lasers, making them ideal for eye-safe 1.54 μm Er glass lasers. Cocrystals can also operate at 1.44 μm and 1.34 μm laser wavelengths, providing a cost-effective solution for developing compact, low-cost nanosecond and sub-nanosecond pulse lasers. With their broad application range, Cocrystals are becoming increasingly popular in various laser systems.
