Yttrium orthovanadate (YVO 4) is a transparent crystal. Undoped YVO 4 is also used to make efficient high-power polarizing prisms similar to Glan–Taylor prisms. [1] There are two principal applications for doped yttrium orthovanadate: Doped with neodymium it forms Nd:YVO 4, an active laser medium used in diode-pumped solid-state lasers. [2]
Neodymium-doped yttrium orthovanadate (Nd:YVO 4) is a crystalline material formed by adding neodymium ions to yttrium orthovanadate. It is commonly used as an active laser medium for diode-pumped solid-state lasers. It comes as a transparent blue-tinted material. It is birefringent, therefore rods made of it are usually rectangular.
They most commonly emit light at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal. [24] Neodymium-doped crystals usually produce a principal wavelength of 1064 nm, but with the proper reflective coating mirrors can be also made to lase at other non-principal neodymium ...
They most commonly emit a beam at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal (Nd-doped crystals usually produce a principal wavelength of 1064 nm, but with the proper reflective coating mirrors can be also made to lase at other "higher harmonic" non-principal neodymium ...
Blue DPSSLs use a nearly identical process, except that the 808 nm light is being converted by an Nd:YAG crystal to 946 nm light (selecting this non-principal spectral line of neodymium in the same Nd-doped crystals), which is then frequency-doubled to 473 nm by a beta barium borate (BBO) crystal or LBO crystal. Because of the lower gain for ...
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
