Nd:YAG crystal is the most widely used solid-state laser material today. Now, we are able to stably supply the quality of Nd:YAG rods with high optical homogeneity, high damage threshold, consistent performance, high processing accuracy. In order to meet OEM and R&D requirements, an improved quality assurance procedure has been implemented in Newphotons during the crystal growing and fabricating process, Nd:YAG rods with stable quality and quick delivery are available.
