Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [ 2 ] ) in a hexagonal or an orthorhombic, perovskite -like form, and the monoclinic Y 4 Al 2 O 9 (YAM [ 3 ] ).
Er:YAG laser rod. An Er:YAG laser (erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium-doped yttrium aluminium garnet (Er:Y 3 Al 5 O 12). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light. [1]
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...

Yttrium, iron, aluminium, and gadolinium garnets (e.g. Y 3 (Fe,Al) 5 O 12 and Y 3 (Fe,Gd) 5 O 12) have important magnetic properties. [15] YIG is also very efficient as an acoustic energy transmitter and transducer. [74] Yttrium aluminium garnet (Y 3 Al 5 O 12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated ...

Nd-doped YCOB (Nd:YCa 4 O(BO 3) 3) is a nonlinear optical crystal, which is commonly used as an active laser medium. It can be grown from a melt by the Czochralski technique. It belongs to the monoclinic system with space group C s 2-Cm. Each neodymium ion replaces a yttrium ion in the YCOB crystal structure.
Over the years the neodymium laser became one of the most used lasers for application purposes. The success of the Nd 3+ ion lies in the structure of its energy levels and in the spectroscopic properties suitable for the generation of laser radiation. In 1964 Geusic et al. [67] demonstrated the operation of neodymium ion in YAG matrix Y 3 Al 5 ...
