Neodymium-doped gadolinium orthovanadate

Laser gain medium From Wikipedia, the free encyclopedia

Neodymium-doped gadolinium orthovanadate, typically abbreviated as Nd:GdVO4, 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.

Optical properties

The luminescence lifetime (spontaneous emission lifetime) is a function of Nd3+ ion concentration as seen in the table.
