PPSLT for SHG (Second Harmonic Generation)
Request for Quotation >PPSLT for SHG
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
