Single crystals of potassium-yttrium tungstate (KYW:Yb), doped with ytterbium ions, α-KY (WO4) 2-Yb3 +, are used in lasers to generate ultrashort pulses (50-200 fsec). KYW:Yb single crystals are a unique laser material that allows laser diodes to be used most efficiently (efficiency> 50%).

Monocrystals of our manufacture are characterized by high quality, high radiation resistance, low lasing threshold, high efficiency. We manufacture active elements of diameter 3-10 mm, length up to 80 mm according to customer’s drawings. We have possibility to grow crystals KGW with other activators.
