Physics:Neodymium-doped gadolinium orthovanadate

From HandWiki
Short description: Laser gain medium

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 [1]
0.9 97 [2]
1.0 95 [3]
1.2 90 [4]
2.0 44 [5]
