KTP crystals «In Stock»

Potassium titanyl phosphate (KTiOPO4, KTP) crystals are advantageous due to their high nonlinearity, great mechanical stability, high optical quality, and transparency range of 350 nm - 4,5 µm. These features determine the wide application of KTP crystals as a nonlinear medium. It is an excellent solution for frequency doubling applications of Nd-doped lasers, especially for low and medium power applications, both intra- and extra-cavity design. Besides, these crystals can be used as a nonlinear OPO medium for IR generation up to 4 µm and used as a pump source for mid-IR nonlinear crystal-based optical parametric oscillators, such as ZGP OPO. KTP is susceptible to photochromic damage (grey-tracking), which causes the deterioration of nonlinear conversion efficiency. 4Lasers provide high grey track resistance (HGTR) KTP crystals as a solution, which significantly improves the grey-track resistance and overall performance. HGTR KTP crystals extend the use of KTP as a nonlinear medium to high-power applications.
