Nd:YVO4 Crystals

Nd:YVO4 (Neodymium doped yttrium Vanadate) crystal is one of the most efficient laser host crystals for all-solid-state laser diode pumped lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient and wide absorption bandwidth at pump wavelength, high laser induced damage threshold as well as good physical, optical and mechanical properties make it an excellent crystal for high power, stable and cost-effective diode pumped solid-state lasers.

Nd:YVO4 crystals with diffusion bonded undoped YVO4 endcaps are also available from Newlight Photonics. Please visit here

Laser Properties:

The Nd:YVO4 crystal has large stimulated emission cross-sections at both 1064nm and 1342nm. The stimulated emission cross-section of an a-axis cut Nd:YVO4 crystal at 1064nm is about 4 times higher than that of the Nd:YAG crystal. Although the lifetime of Nd:YVO4 is about 2.7 times shorter than that of Nd:YAG, the slope efficiency of a Nd:YVO4 laser can be very high if the laser cavity is properly designed thanks to its high pump quantum efficiency, . Table 1 lists the major laser properties of Nd:YVO4 in comparison with those of Nd:YAG. Table 2 gives the performance of a few examples of Nd:YVO4 lasers.
