Q-switch & Polarization Crystals

Co:Spinel (Co:MgAl2O4)

Cobalt-doped magnesium aluminate spinel, Co:MgAl2O4, is a saturable absorber for passive Q-switching around 1.2–1.6 µm, including Er:glass systems. Initial transmission, aperture and coating determine the operating confi...

Cr:YAG

Cr4+:YAG provides passive Q-switching for Nd- and Yb-based lasers in the 0.8–1.2 µm range. Selecting initial transmission and absorber dimensions sets the loss and energy-storage conditions without an external electro-op...

TGG

Terbium gallium garnet, TGG, is a magneto-optic material for Faraday rotators and isolators. Its stated working region is 400–1100 nm excluding 470–500 nm; the optical arrangement uses nonreciprocal polarization rotation...
