Dream Lasers grows high quality, Cr-doped colquiriite crystals using  the  Czochralski technique. This family of materials  includes  LiSAF, LiSGaF and LiCAF.The use of high  quality starting  materials for crystal growth and measurement of Cr concentration using absorption spectroscopy assures that each crystal will perform to customer specifications.

Our general LiSAF, LiSGaF and LiCAF production capabilities include:

Rod sizes from 2mm to 16mm in diameter and from 1mm to 180mm in length 
Orientation of rod axis to crystal a-axis within 2 degrees
Polished and AR coated barrels
