Low absorption grade single crystal diamond

Element Six’s low absorption CVD diamond enables lasers to operate at higher powers over a wider range of wavelengths


  • Low absorption single crystal has an absorption coefficient less than 0.005 cm @ 1064 nm - more than an order of magnitude lower than our standard grade 
  • Can be combined with our low birefringence manufacturing techniques for select crystal orientations
