Nd:YVO4 has a larger stimulated emission cross-section and a higher absorption coefficient for pump light compared to Nd:YAG, . It is an excellent laser crystal suitable for manufacturing laser diode pumps, especially for low and medium power lasers. It can be used to produce all-solid-state lasers with output ranging from near-infrared, green, blue to ultraviolet. Currently, Nd:YVO4 lasers have been widely used in various fields such as material processing, machinery, wafer inspection, medical diagnosis and more.
High absorption efficient over a wide pumping bandwidth around 808nm
Larger stimulated emission cross-section at the lasing wavelength of 1064nm
Linearly polarized emission as the uniaxial crystal with large birefringence
