Passive Q-Switch V:YAG Crystal Yttrium-Aluminum Garnet Crystals Customizable
The crystals of Yttrium-Aluminum Garnet (YAG) doped with three-valence vanadium V³+ in tetrahedral position is relatively new material for passive Q-switching. V:YAG has working as efficient Q-switch for lasers operating in the 1.0~1.5 µm region. The absorption band between 1.0~1.5 µm is attributed to ³A2 →³T2 transition of V³+ ion in tetrahedral position of garnet lattice. Concentration of V³+ in tetrahedral position is controlled by growth and annealing conditions. The efficient Q-switching of lasers operating at both 1.064 and 1.3 micron has been obtained with a number of active mediums such as Nd:YAG, Nd:YVO4, Nd:KGd(WO4)2 under flash-lamp and laser diode pumping.
