About Pockels Cells
Pockels electro-optic effect describes the phase changes produced in polarized light passing through certain uniaxial crystal materials which are under the stress of an electric field. The effect is a linear function of the voltage which is applied parallel to the crystal optical axis in the same direction as the incident light. – From “Pockels cells Primer”, by Robert Goldstein” See the full atricle here.
Please see below for Pockels cells for the drivers please see the electro-optics page.

PICOSECOND POCKELS CELLS MODELS 1111 / 1112Lasermetrics Models 1111 and 1112 are the fastest switching Pockels Cell Electro-Optic Modulators currently available. The Model 1111, a single crystal device and the 1112, a dual crystal model have demonstrated rise times of 40 picoseconds and 85 picoseconds respectively. They attain, within a few percent, the maximum theoretical speed possible for devices of their physical clear aperture. The Model 1112 operates at one half the voltage required by the single crystal Model 1111 by using two crystals optically in series and electrically in parallel. Both devices are configured to present a 50 Ohm impedance to the electrical driving pulse. PICOSECOND POCKELS CELLS – MODELS 1111 / 1112 |

POCKELS CELL ELECTRO-OPTIC Q-SWITCHES 1145 SERIESSeries 1145 Q-switches are miniature electro-optic devices (Pockels cells) intended for use with the latest compact size lasers. They are useful for Q-switching, cavity dumping and laser pulse extraction in regenerative amplifiers. Other applications include polarization rotation, laser beam chopping,slicing and pulse picking. They accommodate the most demanding high peak power laser applications. All models within the series utilize a rugged internal crystal support and hermetic sealing system. The devices incorporate highest quality crystals, fused quartz windows and high damage threshold antireflection coatings. POCKELS CELL ELECTRO-OPTIC Q-SWITCHES 1145 SERIES |

BBO POCKELS CELL Q-SWITCHES 1150 SERIESBBO (Beta Barium Borate) is noted for its excellent optical quality and low strain birefringence. This results in high extinction ratios and low wavefront distortion. Low absorption provides excellent transmission efficiency in the UV and near IR. Qswitches fabricated from BBO can be operated at high repetition rates and high average power. Operation of BBO modulators and Q-switches from single shot to repetition rates of more than 50 kHz is possible with negligible piezoelectric response. Series 1150 devices are compatible with FastPulse’s Laser Pulse Gating Systems. They are used in regenerative laser amplifiers for seeding and gating, Laser Pulse Chopping and Polarization Rotation applications. One advantage of BBO devices is that they do not induce significant piezoelectric ringing on the transmitted laser beam. BBO has a useful optical wavelength range from 250 nm to 2100 nm. Transmittance, in the 350 to 1100 nm range, with “V” type narrow band, high efficiency Anti-Reflection coated windows is approximately 98.5%. |
