Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, 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 of similar size.[1] It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as red chromium ion in ruby lasers. Nd:YAG Rods Neodymium doped Yttrium Aluminum Garnet (Nd:YAG) is the most commonly employed solid state lasing medium for material processing applications. Nd:YAG has relatively good optical absorption and conversion efficiency, low lasing threshold and good thermal dissipation for high power operation.

Advantage of Nd:YAG Crystal During the last decade, Nd:YVO4 has been developed as a promising substitutes for Nd:YAG in diode-pumped lasers due to its high absorption and emission cross-sections. However, the applications of Nd:YVO4 are limited due to its poor physical-mechanical properties and growth difficulty etc. Now, we have developed the high-doped Nd:YAG (SUPER-Nd:YAG) recently. It shows high absorption cross-section and have many advantages over Nd:YVO4: Material: Nd(Ce)YAG Cr:YAG Dimension: Dia. 3.00mm Thickness: 55.00mm Tolerance : +/-0.10mm YAG laser optically pumped by Xenon or Krypton lamp The high neodymium-ion doped YAG has been grown by the novel technique-Temperature Gradient Technique (TGT). The Nd concentration can be doped up to 3%. As large as 100x80mm bulk crystals with excellent optical homogeneity, less scattering particles, low dislocation density have been obtained. Neodymium-doped yttrium aluminum garnet (Nd:YAG) crystal can excites pulsed laser or continuous laser. The emitted laser is infrared wavelength 1.064μm. The superior basic properties make it often used in Near-far infrared lasers, frequency-doubled and triple-frequency, Nd:YAG are widely used in scientific research, medical, industrial and military lasers. VY Optoelectronics Co.,Ltd. can also produce YAG single crystal products, CTH: YAG, Er:YAG, Ho:YAG, Yb:YAG, Undoped YAG and so on, with the maximal diameter of 4-6 inches, as well large-size magneto-optical single crystal TGG and TSAG .

Baijing Optoelectronics supplies Nd:YVO4, neodymium-doped yttrium vanadate, an excellent laser crystal for laser-diode pumping, especially at low and medium powers. Compared with Nd:YAG, Nd:YVO4 has higher pump absorption and a larger stimulated-emission cross-section. Nd:YVO4 lasers are widely used in machinery, material processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and data storage. The English section describes yttrium vanadate (Nd:YVO4) as one of the most efficient host crystals for diode-pumped solid-state lasers. A large stimulated-emission cross-section at the laser wavelength, high pump absorption and broad pump-absorption bandwidth, high laser-induced damage threshold, and good physical, optical, and mechanical properties make Nd:YVO4 suitable for high-power, stable, cost-effective diode-pumped solid-state lasers. Recent developments show that Nd:YVO4 can produce powerful, stable infrared, green, and blue lasers by combining Nd:YVO4 with frequency-doubling crystals.
