Frequently Asked Questions — KTP Crystal

What is a KTP crystal used for?
KTP (Potassium Titanyl Phosphate) is a widely used nonlinear optical crystal for frequency conversion and electro-optic applications. It is best known for efficient second-harmonic generation (SHG), especially converting 1064 nm infrared light to 532 nm green light.
Why is KTP commonly used for 532 nm green lasers?
KTP has a high effective nonlinear coefficient, wide angular and temperature acceptance bandwidth, and good optical damage resistance, making it highly efficient and stable for SHG of Nd:YAG and Nd:YVO₄ lasers.
How does KTP compare with LBO or BBO?
Compared with LBO and BBO, KTP offers higher nonlinear efficiency and easier phase matching, but with lower damage threshold. LBO is preferred for very high-power systems, while KTP is ideal for compact and efficient green laser generation.
What wavelength range does KTP support?
KTP has a wide optical transmission range from approximately 350 nm to 4.5 µm, making it suitable for visible and near-IR laser applications.
Can KTP be used for electro-optic applications?
Yes. KTP exhibits a strong electro-optic effect and is commonly used in Q-switches, modulators, and other EO devices in solid-state laser systems.
What crystal forms and cuts are available?
KTP crystals are available as bulk crystals, prisms, rods, and custom-cut geometries with specific phase-matching orientations for SHG, OPO, and EO applications.
Do you offer optical polishing and AR coatings?
Yes. Laser-grade optical polishing and optional anti-reflection (AR) coatings optimized for your operating wavelength are available upon request.
Are KTP crystals suitable for research and OEM use?
Absolutely. Our KTP crystals are supplied to universities, research laboratories, and laser manufacturers for both R&D and production applications.
