Transparent YAG-based ceramics for laser applications

Polycrystalline YAG (Y3Al5O12) doped with rare earth elements (REE) is a strategic functional material as laser source for high power Diode Pumped Solid State Lasers(DPSSL).
Compared to the more commonly used single crystals, transparent YAG ceramic can widen the laser applications:
It can be highly doped
It is faster to produce
It can be shaped in complex architectures.
