Nd: YAG crystal rod is used in Laser marking machine and other laser equipment.
It is the only solid substances that can work continuously at room temperature, and is the most excellent performance laser crystal.
Nd:YAP AlO3 perovskite (YAP) is a well known host for solid state lasers. The crystal anisotropy of YAP offers numerous advantages.It permits a small tuning of wavelength by varyingthe wave vector direction in the crystal. Furthermore, the output beam is linearly polarised.
