PPKTP (Periodically Poled KTP) is a popular nonlinear material.
PPKTP material is widely recognized for these features:
Supports all nonlinear applications within KTP transparency range
It doesn’t have the phase matching limitations of bulk KTP
3* larger effective nonlinear coefficient compared to bulk KTP
Highest nonlinear coefficient
Free of walk-off
Large quantities for OEM mass-production as well as small quantities for R&D
Broad phase-matching range
Type 0 or type II interaction
We provide the following products:
1) Single PPKTP element
2) PPKTP for SHG: Second Harmonic Generation (SHG) is a nonlinear optical process whereby the pumping wavelength generates a new wavelength that is half of the input wavelength or double frequency.
3) PPKTP DFG: Difference Frequency Generation (DFG), generation of light with a frequency that is the difference between two other frequencies.
4) PPKTP SFG: Sum Frequency Generation (SFG) is a non-linear optical process. This phenomenon is based on the annihilation of two input photons at angular frequencies ɯ1 and ɯ2 while, simultaneously, one photon at frequency ɯ3 is generated.
5) PPKTP OPO: we provide the following types of PPKTP OPO:
