PPKTP SFG (Sum Frequency Generation)

Request for Quotation >


PPKTP 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

Sum-frequency generation (SFG) is a non-linear optical process.

This phenomenon is based on the annihilation of two input photons at angular frequencies \omega_1 and \omega_2 while, simultaneously, one photon at frequency \omega_3 is generated.
