Under DevelopmentYAG* Ceramics for Laser Applications

  • Yttrium Aluminum Garnet

YAG is a garnet-shaped crystal formed as a composite oxide of yttrium and aluminum.
We are developing YAG ceramics (polycrystalline) with superior optical properties.

Application Example

Flash LiDAR

Laser light source for processing machinery

Amplifier for high-power laser
(e.g.: MOPA system)

Customer Values

Compared with single crystal, YAG Ceramics (polycrystalline), whose transmittance is equivalent with that of single crystal, has following advantages.

  • High mass productivity
  • Large size (up to 6 inches)
  • Easy to bond with other materials or with other YAG
  • Homogeneous dopant concentration
  • High dopant concentration (up to Nd:4at%)
