專業KDP, DKDP crystals廠商

Potassium dihydrogen phosphate (KH2PO4, KDP) and potassium dideuterium phosphate (KD2PO4, DKDP) crystals are one of the oldest used nonlinear materials. DKDP and KDP are known as analogs, though their properties differ due to DKDP deuteration. They both exhibit excellent ultraviolet transmission and high damage threshold. The nonlinearity of these crystals is relatively low, these crystals can be grown in large size. They found their application as nonlinear frequency doublers, triplers, and quandruplers of Nd-doped lasers and as Q-switch devices for Ti:Sapphire, Alexandrite, Nd-doped lasers. The main drawback is that these crystals are highly hygroscopic, therefore sealed housing and dry operating conditions have to be ensured.
