PPKTP SFG (Sum Frequency Generation)
Request for Quotation >PPKTP SFG
PPKTP is a popular nonlinear material.
PPKTP material is widely recognized for these features:
- Supports all nonlinear applications within KTP transparency range
- It doesn’t have the phase matching limitations of bulk KTP
- 3* larger effective nonlinear coefficient compared to BULK KTP
Sum-frequency generation (SFG) is a non-linear optical process.
This phenomenon is based on the annihilation of two input photons at angular frequencies and
while, simultaneously, one photon at frequency
is generated.
