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:
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 asf100x80mm bulk crystals with excellent optical homogeneity, less scattering particles, low dislocation density have been obtained.

·SUPER-Nd:YAG shows high absorption coefficients at pumping wavelengths. Therefore, a crystal short-in length (e.g.1mm) is preferred and compact microchip lasers can be constructed by using SUPER-Nd:YAG.
