Item: YAG-007
Product Name: Nd:GGG
Nd:GGG is an optimal crystal for solid-state heat-capacity laser because of its high thermal diffusivity and large diameter resulting from its easiness of growth with flat interface between solid and melt. It is also a candidate for high average power laser with high pulse energy.
Advantages of Nd:GGG Crystals
- Suitable for high energy output at heat-capacity operation
- Large crystal diameter with good optical quality
