Pockels Cell Half-Wave Voltage calculator
Vπ for a longitudinal/transverse EO modulator from r-coefficient and geometry.
Category: Active Optics
Formula: Vπ = λ·d/(n³·r·L) (transverse phase modulator)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Wavelength | lam | nm | 1064 |
| Refractive index n | n | 2.2 | |
| EO coeff r (pm/V) | r | 30.9 | |
| L/d ratio | LD | 1 |
Result with the default inputs
- Vπ: 3233.8145 V
Open it with your own values: put each input in the address as a parameter, for example /calculators/pockels-cell-half-wave-voltage?lam=1064. A unit other than the listed one goes in <parameter>_unit.
