Introduction

Neodymium Doped Yttrium Aluminum Garnet (Nd:YAG) Crystal. Nd:YAG crystal is the most widely used solid-state laser material today. Now we are able to stably supply quantity of Nd:YAG rods with high optical homogeneity consistent performance high processing accuracy and on time delivery.
