New Polar Oxysufide for Nonlinear Optical Applications


Reference #: 01327

The University of South Carolina is offering licensing opportunities for New Polar Oxysufide for Nonlinear Optical Applications



Non-linear optical materials are commonly used for frequency doubling diode-pumped solid state lasers such as Nd:YAG or other Nd-doped lasers, and are also used as optical parametric oscillator for near IR generation. They are also used as an electro-optic modulator, optical waveguide material, and in directional couplers.


Invention Description:

Synthesized single crystals of a new polar material that has an SHG response twice that of KDP and is phase-matchable.


Potential Applications:

•       Improvements to high power lasers

•       Optical communications

•       Signal processing

•       Spectroscopy


Advantages and Benefits:

The Second Harmonic Generation (SHG) was measured and found to be twice as good as Potassium Dihydrogen Phosphate (KDP), one of the most widely-used materials in high power laser applications. These measurements indicate that not only is the SHG response twice that of KDP, but these crystals are a phase-matchable non-linear optical material.
