PPKTP for SHG (Second Harmonic Generation)

Request for Quotation >


Periodically Poled KTP (PPKTP) is a popular nonlinear material.

PPKTP material is widely recognized for these features:

  • It can be customized for all nonlinear applications within the KTP transparency range
  • It doesn’t have the phase matching limitations of bulk KTP.
  • Its effective nonlinear coefficient is approximately three times larger than that of bulk KTP.

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.
