Nd YAP laser crystal for high-power operation at the 1300nm and 2940nm laser
Description
The chemical formula of Nd: YAP is Nd3+: YAlO3, and the structure is distorted perovskite, belonging to oblique hexagonal crystal system, and spatial group is Pbnm, whose axes a, b and c are perpendicular to each other, belongs to negative uniaxial crystals and is anisotropic. Among the numerous neodymium-doped laser crystals, Nd: YAP crystal not only has high thermal conductivity, but also has a larger excited emission cross section at 4F3/2–4 I13/2 transition. They are one of the most effective laser crystals known at present for the high-power operation at the 1.3 mm, the crystal is mainly pumped by LD. 1.3 mm lasers are widely used in the field of medicine, optical fiber communication and military. What’ s more, water molecule has good absorption at this laser band. Which makes it have a very good hemostatic ability, and widely used in laser therapy, such as hemostasis, neurosurgery, resection of pathological tissues and wrinkle removal. In addition, Nd: YAP crystal has natural birefringence characteristics, which is very beneficial to overcome the thermal depolarization and nonlinear frequency transformation of laser.
