PPMgLN for SHG (Second Harmonic Generation)

Request for Quotation >


Periodically Poled Magnesium doped Lithium Niobate (PPMgLN) is an efficient nonlinear optical material for frequency conversion applications in the visible and mid-IR wavelength range

PPMgLN material is widely recognized for these features:

  • High nonlinear coefficient
  • High conversion efficiency
  • Perfectly suited for compact low power solid state laser systems
  • High damage threshold and high efficiency
  • Excellent for small size, cost effective laser systems

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
