Neodymium-doped gadolinium orthovanadate

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.

Nd concentration (atom %)	Luminescence lifetime (μs) @ 1064 nm	Reference
0.5	107
0.9	97
1.0	95
1.2	90
2.0	44
