Co2+: MgAl2O4 is a relatively new saturable absorption passive Q-switch material, suitable for 1.2～1.6μm laser emission, especially suitable for the 1.54μm eye-safe Er glass laser. Passive Q-switching or saturable absorber can generate high-power laser pulses without using electro-optic Q switching, which can effectively reduce the size of the device and avoid the use of high-voltage power.
Spinel is a hard, stable crystal that can be polished to the desired index. Cobalt particles replace magnesium ions without additional charge compensation. In the 1.3μm attachment, it has a particularly high excited-state absorption cross-section (3.5×10-19 cm2), so that the flash lamp and the laser-pumped Er glass laser do not need to be focused in the cavity.
