Potassium Titanium Oxide Phosphate (KTiOPO4, KTP for short) crystal


AG laser crystal (2)AG laser crystal (1)AG laser crystal (3)AG laser crystal (4)NDYAG crystal rod (1)NDYAG crystal rod (3)NDYAG crystal rod (2)


The KTiOPO4 (KTP) crystal grown by the hydrothermal method is a nonlinear optical crystal with very good performance. It has a large nonlinear coefficient, a wide range of allowable temperature matching and allowable angle matching, and it is resistant to dust and High optical damage threshold, stable chemical and mechanical properties, etc., can be used for laser frequency doubling, sum frequency, difference frequency, parametric oscillation, optical waveguide devices, electro-optical modulators, etc., widely used in military scientific research, medical treatment, marine optics, laser weapons And environmental remote sensing monitoring and other fields. It has the following characteristics:

① High resistance to laser damage, high anti-gray performance, high optical quality

② SHG phase matching angle (1064-532nm): 23.4°(25℃)

③Conductivity: 10-10/Ω·cm level;

④Domain structure: single domain
