SFG / DFG Wavelengths calculator
Sum- and difference-frequency wavelengths for two input photons.
Category: Nonlinear Optics
Formula: 1/λsfg = 1/λ1+1/λ2 · 1/λdfg = |1/λ1−1/λ2|
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| λ1 | l1 | nm | 800 |
| λ2 | l2 | nm | 1064 |
Result with the default inputs
- SFG: 456.6524 nm
- DFG: 3224.2424 nm
Open it with your own values: put each input in the address as a parameter, for example /calculators/sfg-dfg-wavelengths?l1=800. A unit other than the listed one goes in <parameter>_unit.
