Potassium Titanyl Phosphate (KTiOPO3 or KTP) Crystals are a versatile kind of optical crystals. The advantages of KTP crystals include high non-linear coefficient and damage threshold, wide acceptance angle, substantially temperature-stable phase-matching characteristics, and non-hygroscopicity. These traits, combined with its excellent transmission in the visible and near-IR wavelength range, have bulit up their prevalence in the field of Nonlinear Optics (NLOs). KTP crystals could be extensively utilized in the Second Harmonic Generation (SHG) of Nd:YAG lasers. When Shalom's KTP is applied outside the cavity of a 900mJ injection-seeded Q-switch Nd:YAG laser, the resultant output is a 700mJ green laser, suggesting a highly efficient conversion of over 80%. Other applications include OPO/OPA/OPG to obtain 600nm-4500nm light output and SFM.
On the other hand, KTP crystals also manifest promising Electro-Optical properties, including great electro-optical coefficients and low dielectric constants, etc. Because KTP crystals virtually produce no parasitic oscillation, the crystals are attractive options for manufacturing EO modulators, Q-switches, EO deflectors, waveguides, etc.
Hangzhou Shalom EO offers off-the-shelf and custom KTP Crystals with various coating options and rigorous QC inspection, plus aperture values up to 40x40mm are available. Standard coating options include: AR, HR, HT, PR dual-wavelength coatings for SHG, other custom coatings could also be tailored. For applications with higher power levels, High Gray Track Resistance (HGTR) KTP crystals are also procurable in Shalom EO.
