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.
