Double Crystal KD*P Pockels cells
Standard and Compact Options
Ideal for Q-switching & Pulse-Picking at lower voltage.

Two Crystal Longitudinal Mode Pockels Cells

As with all our other longitudinal Pockels cells, these can be supplied in one, two or four terminal configurations (as seen in the above picture) and may be supplied either with index matching fluid filling the space between the crystals and the windows (preferred) or dry, with or without anti-reflection coatings on the crystals. Tilted off windows and/or wedged crystals may be specified (there may be a small charge for the latter) if required to control interference effects caused by multiple reflections.
We can produce two crystal Pockels cells in any aperture size up to even 25mm, although 8mm, 10mm and 12mm are the most common. We also manufacture two crystal devices in our compact Pockels cell range as well as our ultra fast Pockels cell (UPC) in both single and double crystal versions. Please contact us if you have any special requirements not met by what you have seen here.
