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]
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 ] ).
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 ...

Laser rods (from left to right): Ruby, Alexandrite, Er:YAG, Nd:YAG The active laser medium (also called a gain medium or lasing medium ) is the source of optical gain within a laser . The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously ...
Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition Y 3 Fe 2 (FeO 4) 3, or Y 3 Fe 5 O 12. It is a ferrimagnetic material [1] with a Curie temperature of 560 K. [2] YIG may also be known as yttrium ferrite garnet, or as iron yttrium oxide or yttrium iron oxide, the latter two names usually associated with powdered ...
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 ...
In the latter case, the f-block elements are split into half: the first half (La–Eu) form the cerium group, and the second half (Gd–Yb) together with group 3 (Sc, Y, Lu) form the yttrium group. [23] The reason for this division arose from the difference in solubility of rare-earth double sulfates with sodium and potassium.
