Nd:YVO4

280.00310.00

Nd:YVO4 crystals are usually used in lasers to generate the same wavelength radiation as Nd:YAG ( 1064 nm ). Other important emission wavelengths of this crystal are 914 and 1342 nm. These types of lasers most comonly are pumped with diodes, however they can be lamp pumped too. Compared with Nd:YAG, Nd:YVO4 has a higher pump absorption rate with broader wavelength range for pumping. Nd:YVO4 also has a shorter upper state lifetime which reduces thermal loss effects.
