PPSLT for SHG (Second Harmonic Generation)

Request for Quotation >


PPSLT (Periodically poled stoichiometric Luthium Tantalite) is a promising nonlinear optical material suitable for compact solid state laser systems in which  output power of a few Watts is required.

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

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. When using ND:Yag wavelength 1064nm the SHG will become 532nm which is within the green light spectrum
