Pockels Cells
from G&H
G&H are a leading crystal grower with decades of electro-optic device design experience. They manufacture a comprehensive range of Pockels Cells for applications in wavelengths from the UV to the IR. Factors such as average power, repetition rate and the design configuration determine the recommended type of device.
Utilizing proprietary crystal growth, fabrication, and polishing techniques, we manufacture both longitudinal and transverse electrode configuration Pockels cells in beta barium oxide (BBO), cadmium telluride (CdTe), potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (KD*P).
These operate by virtue of the Pockels effect, also known as the linear electro-optic effect.
To identify, which pockels cell is the right one for your application, please fill out the questionnaire and send it back!

Pockels Cells Driver
from G&H
G&H Pockels cell drivers have been developed to complement our range of Pockels Cells. High quality components are integrated into our designs to maximize lifetime, safety, and reliability.
These Pockels cell drivers include the Q-series Q-switch drivers and R-series regenerative amplifier drivers. Q-switch drivers provide a fast rise time followed by a longer decay time. Regenerative amplifier drivers have a square pulse with a fast rise and fall time, adjustable pulse width and may be operated to 100 kHz or more.
Applications
Ideal for development of Q-switched lasers for:
- Medical
- Imaging
- Engraving
- Cutting metal
- Micro processing
- Range finding
- Holography
- Welding
- Glass cutting
- Spectroscopy
- and many more applications
