AR coated 1064nm Nd Yag laser crystal rod for laser
Nd: YAG single crystal is the most important laser crystal

The working material of neodymium doped yttrium aluminum garnet laser is yttrium aluminum garnet crystal doped with trivalent neodymium ion (Nd3 +). Its chemical expression is Y3Al5O12: Nd3 +, which is light purple and usually processed into a round rod.

The thermal conductivity of the crystal is good, and the laser oscillation characteristics are less affected by the temperature rise of the crystal. Therefore, the laser can operate continuously under the condition of continuous optical pump (continuous krypton lamp excitation) or pulse operation under the condition of high repetitive pulse (pulse xenon lamp excitation), and the output laser wavelength is 1064nm
