Nd:YVO4

Nd:YVO Crystals

Nd:YVO4 (Neodymium doped yttrium vanadate) Crystal is a kind of crystal with excellent performance, which is suitable for manufacturing laser diode pumping, especially for low and medium power lasers. Now lasers have been widely used in many fields such as Machinery, Material Processing, Spectroscopy, Crystals inspection, Display, Medical Inspection, Laser Printing, Data Storage and so on.

Key Wavelength: 914nm / 1064nm / 1342nm

  • As high as about five times larger absorption efficient over a wide pumping bandwidth around 808nm.
  • As large as three times larger stimulated emission cross-section at the leasing wavelength of 1064nm.
  • Lower lasing threshold and higher slope efficiency
  • As a uniaxial crystal with a large birefringence, the emission is a linearly polarized.
  • Due to the wider pumping bandwidth of Nd:YVO4, its laser performance can better adapt to the temperature change of LD.
  • Due to the large cross-section of absorption, the attraction coefficient is large, and due to the small thermal conductivity, Nd:YAG is suitable for the thin-scale pumping of medium and low power lasers.
