Nd:GdVO₄

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]

gollark: They radiate tons of heat and you can perfectly predict their orbital path given previous knowledge of it.

gollark: Space things are on the whole not very stealthy anyway.

gollark: But it would probably be hard to manage at such ridiculous velocity.

gollark: I assume they mean inertial guidance or something, where it works out its position based on acceleration/gyroscope data.

gollark: Cynical answer: you are not, mostly, paying for actual education, which is increasingly cheap via the internet, but inherently scarce social status from either going to a prestigious college or having a degree at all.
