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.

  • Wide pump band of 600 - 800 nm
  • High Slope Efficiency
  • High optical quality
  • Operates in a long-wavelength, high water peak region
