KTP

KTP crystals is the most commonly used material for frequency doubling of Nd-doped lasers.

It is widely used for frequency mixing to generate Red/Green/Blue output, and for OPO and OPA to generate visible to mid-infrared tunable output. It is also used for many E-O devices such as Q-switches and E-O modulators.

KTP is widely used in both commercial and military lasers including laboratory and medical systems, range-finders, lidar, optical communication and industrial systems.


Advantages

Large nonlinear optical coefficient

Wide angular bandwidth and small walk-off angle

Broad temperature and spectral bandwidth

High Electro-Optics(E-O) coefficient and low dielectric constant

Non-hygroscopic, chemically and mechanically stable


 

 


Applications


Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output
