Co2+:MgAl2O4 Laser Crystal is a relatively new material for passive Q-Switching in lasers emitting from 1.2 to 1.6 um.
In particular, for eye-safe 1.54um Er:glass laser, but also works at 1.44um and 1.34um wavelengths.
Passive Q-Switching or saturable absorber, Co2+:MgAl2O4 Crystal can cause high power laser pulse without using electric-optic switching, also can compact the device.
Saturable-absorber Q switching of a neodymium-doped YAlO(3) laser at 1.34 microm and an erbium-doped glass laser at 1.54 microm with a Co2+:MgAl2O4 crystal was demonstrated.
Q-switched 1.34-microm pulses of 19-mJ energy and 60-ns duration and Q-switched 1.54-microm pulses of 2.7-mJ energy and 75-ns width were obtained.
The ground-state absorption cross sections of the Co2+:MgAl2O4 crystal were estimated to be (2.8 +/- 0.4) x 10(-19) and (3.5 +/- 0.6) x 10(-19) cm(2) at 1.34 and 1.54 microm, respectively.
