Electro-optic Pockels Cell
■Quickly switching the polarization direction of the light beam ■The Pockels effect is an electronic effect that causes a significant linear change in refractive index under an appropriate electric field, allowing for a response much faster than that of acousto-optic devices ■Pockels cells from Inrad Optics can also be used for phase modulation, but they do not achieve the high efficiency of devices specifically designed for phase modulation ■To prevent the beam from experiencing birefringence in the absence of an electric field, the beam propagates along the optical axis of a single crystal ■A gimbal mount is convenient for adjustments *We can also manufacture according to the specifications specified by the customer.

basic information
**[KD*P Pockels Cell]** - Commonly used in applications from UV to 1.1μm. - Usage in active cavities is limited due to absorption near 1.1μm. - Can be used at longer wavelengths if a few percent absorption is acceptable. **[LiNbO3 Pockels Cell]** - Used at longer wavelengths above 1064nm. - Pockels cells with an electric field set perpendicular to the light propagation direction can be driven at lower voltages than KD*P at 1064nm by selecting the thickness and length of the crystal. - The half-wave voltage becomes very high, but it is optimal for infrared light above 4.0μm. - Inrad Optics offers a damped LiNbO3 Pockels cell that dramatically reduces piezoelectric ringing, allowing for use at higher repetition frequencies. **[BBO Pockels Cell]** - Suitable for the wavelength range from UV to about 2μm. - The electro-optic coefficient is smaller than that of KD*P or LiNbO3, but it can be used at high average output. - BBO generally requires high voltage. - To keep the voltage conditions low, the crystal length is made longer and thinner (resulting in a smaller aperture size).
