Remarkable
- Undoped single crystals are a good alternative to sapphire with a larger transmission range in IR, not birefringent!
- Hard and chemically stable
- The higher refractive index makes it easier to construct lens systems with low aberration
- Maximum possible diameter is 120-140 mm
- A doped YAG crystal is used as an active laser medium or scintillator crystal
