Product Details

Nd:YVO₄ is the most efficient laser crystal for diode-pumped solid-state lasers. The good physical, optical and mechanical properties make Nd:YVO₄ an excellent material for high power, stable and cost-effective diode-pumped solid-state lasers.

Compare with Nd:YAG for diode laser pumping, Nd:YVO₄ lasers have the following advantages:

Lower lasing threshold and higher slope efficiency
Large stimulated emission cross-section at lasing wavelength
High absorption over a wide pumping wavelength bandwidth
Low dependency on pumping wavelength and tend to single mode output
Optically uniaxial and large birefringence emit strongly-polarized laser

Wisoptic provide high quality and large size Nd:YVO₄ and pure YVO₄ crystal as large as 35x35x50mm³ bulk crystal and18 x18x20mm³ finished crystal by very competitive price.
