KTP is the most widely used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level,extra and intra cavity frequency doubled Nd: lasers using KTP have become a preferred pumping source for visible dye lasers and tunable Ti:Sapphire lasers as well as their amplifiers, it is also useful green sources for many research and industry applications.

Advantages:

Large nonlinear optical coefficient

Wide angular bandwidth and small walk-off angle

Broad temperature and spectral bandwidth

High electro-optic coefficient and low dielectric constant

Large figure of merit

Minimum mismatch gradient

Nonhydroscopic, chemically and mechanically stable

Applications:

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

Frequency Mixing (SFM) of Nd Laser and Diode Laser for Blue Light Generation

Parametric Sources (OPG, OPA and OPO) for 0.6um-4.5um Tunable output

E-O Modulators, Optical Switches, Directional Couplers

Optical Waveguides for Integrated NLO and E-O Devices etc.,
