Group Delay Dispersion calculator
Temporal pulse broadening from GDD through dispersive media.
Category: Laser & Ultrafast
Formula: τout = τin·√(1 + (4·ln2·GDD/τin²)²)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Input τ | tau | fs | 100 |
| GDD | GDD | fs² | 5000 |
Result with the default inputs
- Output τ: 170.9331 fs
- Broadening: 1.7093×
Open it with your own values: put each input in the address as a parameter, for example /calculators/group-delay-dispersion?tau=100. A unit other than the listed one goes in <parameter>_unit.
