Co:Spinel PASSIVE Q-SWITCHGo to Product Support
Cobalt-doped magnesium aluminate spinel is a solid state passive Q-Switch material of with peak power around the eye-safe wavelength of 1.5um. Co²⁺ ions substitute for the tetrahedrally coordinated Mg²⁺ ions in the MgAl²O⁴ lattice exhibiting a broad absorption band in the range of 1200-1600. Solid-State passive Q-Switches generating high power laser pulses are attractive because they allow for the development of compact low-cost laser sources without the need for a high voltage power supply. Passive Q-Switches are specified by Optical Density or % Transmission.
