KTA Crystal
Description
KTA crystal (Potassium Titanyl Arsenate) has very similar features to KTP but adds the benefit of a good optical transmission between 3µm and 3.5µm:
Transparent between 0.5µm and 3.5µm
High non-linear optical efficiency
Large temperature acceptance
Lower birefringence than KTP resulting in a smaller walk-off
It is often used as an OPO / OPA gain medium for emission in the 3µm range as well as an OPO crystal for eye-safe emission at high average power.

Frequently Asked Questions
KTA crystal stands for Potassium Titanyl Arsenate crystal. It has similar features to KTP crystal but offers better optical transmission between 3µm and 3.5µm.
The advantages of using KTA crystal include high non-linear optical efficiency, large temperature acceptance, lower birefringence resulting in a smaller walk-off, and good optical transmission between 0.5µm and 3.5µm.
KTA crystal is commonly used in mid-high average power eye-safe lasers, high average power OPA in the mid-IR for high order harmonics, spectroscopy, and gas detection.
KTA crystal offers excellent optical and non-linear optical homogeneity, low absorption of AR-coatings in the 3µm range, high damage threshold of bulk and coatings, and is available in larger cross-sections and lengths.
The specifications of KTA crystal include a transmission range of 0.5µm to 3.5µm, low absorption AR-coating with R<5% over 1.0µm-4.0µm, aperture size up to 15x15mm², length up to 20mm, flatness of <λ/10 @633nm, wavefront distortion of <λ/8 @633nm, and parallelism down to 5".
