Grating Pair Pulse Compression calculator
GDD of a parallel grating pair (Treacy), first order, single pass and double pass.
Category: Laser & Ultrafast
Formula: GDD = −λ³·G/(2π·c²·d²·cos³β) · sin β = λ/d − sin θi
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Wavelength | lam | nm | 800 |
| Separation G (normal) | Lg | cm | 20 |
| Groove period | d | µm | 1 |
| Incidence angle | th | deg | 50 |
Result with the default inputs
- GDD single pass: -181647.8304 fs²
- GDD double pass: -363295.6607 fs²
- Diffraction angle β: 1.9459 °
Open it with your own values: put each input in the address as a parameter, for example /calculators/grating-pair-pulse-compression?lam=800. A unit other than the listed one goes in <parameter>_unit.
