Nd:YAP
Nd:YAP is an excellent laser crystal for high-power solid-state lasers. Because it outputs linearly polarized light, it is especially suitable for solid-state lasers with electro-optic boxes or harmonic generators to obtain high-efficiency laser output . The 1.34μm wavelength laser emitted by Nd:YAP crystal has greater advantages in laser medical applications than the 1.32μm wavelength laser emitted by Nd:YAG crystal.

Atomic Density [Nd1.0%]: 1.26x1020 atoms/cm3 (Nd1.0%) Crystal Structure: Zircon Tetragonal, space group D4h-I4/amd a=b=7.1193A,c=6.2892A Density: 4.22g/cm3
Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.
