Under DevelopmentYAG Ceracmics (Transport ceramics) for Laser
- 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.
Laser light source for processing machinery
Amplifier for high-power laser
(e.g.: MOPA system)
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%)
Nd:YAG bonded with Cr:YAG
Laser Oscillation Test of YAG Ceramics
Successful laser oscillation with similar slope efficiency as single crystals
Transmittance of YAG Ceramics
Excellent optical properties, similar to YAG theoretical transmittance (84%)
