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 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]).
Neodymium-doped yttrium lithium fluoride (Nd:YLF) is a lasing medium for arc lamp-pumped and diode-pumped solid-state lasers. The YLF crystal (LiYF 4) is naturally birefringent, and commonly used laser transitions occur at 1047 nm and 1053 nm. [1] It is used in Q-switched systems in part due to its relatively long fluorescence lifetime.
Neodymium-doped solid state lasers continue to be the laser source of choice for industrial applications. Direct pumping of the upper Nd laser level at 885-nm (rather than at the more traditional broad 808-nm band) offers the potential of improved performance through a reduction in the lasing quantum defect, thereby improving system efficiency ...
Neodymium-doped gadolinium orthovanadate, typically abbreviated as Nd:GdVO 4, is one of the active laser medium for diode laser-pumped solid-state lasers. Several advantages over Nd:YAG crystals include a larger emission cross-section , a pump power threshold, a wider absorption bandwidth, and a polarized output.
