PPSLT SFG (Sum Frequency Generation)

Request for Quotation >


PPSLT is a promising nonlinear optical material suitable for frequency conversion applications over broad wavelength range from UV to mid-IR.

PPSLT material is widely recognized for these features:

  • High damage resistance to high power levels in pump
  • Excellent material for compact solid state lasers.
  • High nonlinear coefficient
  • Excellent for visible light generation applications

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.
