Er:YAG Product Information
Erbium-doped YAG efficiently emits in the infrared at 2940nm, but also pumped for other wavelength emissions such as the 600nm – 800nm range. This general purpose solid state crystal is used in cosmetic, surgical, and dental applications.
Advantages
- Wide pump band of 600 - 800 nm
- High Slope Efficiency
- High optical quality
- Operates in a long-wavelength, high water peak region
