Pockels cell is one of the most important optical components in laser systems from a simple laser shutter to intensifying the output power of lasers. The most common crystals for Electro-optical applications are DKDP, BBO, LiNbO3, KTP and LiTaO3. United Crystals Company provides various electro-optic devices to meet our customer’s different needs.

The cost-efficiency, easy adjustment and large-aperture availability make the DKDP Pockels cells the most common ones since the laser was born. With several-decade dedicated development, United Crystals can provide general DKDP Pockels Cells, dual-crystal DKDP Pockels Cells, large-aperture DKDP cells (over 50mm), Brewster-cut Pockels Cells, general Pockels Cells with Brewster Polarizer, index-matching fluid filled Pockels Cells, and customized cells.

In addition to BBO's excellent non-linear optical properties, it is the exceptional EO material as well, especially for high power systems. Unlike DKDP Pockels cells, BBO Pockels cells work in the transverse mode, which means the actual half (or quarter)-wave voltage could be designed by changing the ratio of the aperture and the length. BBO Pockels cells can work up to 5KHz. For more details of BBO cells, please click here.

LiTaO3, LiNbO3 and MgO:LiNbO3 crystals are not hygroscopic, and they can be used in low power systems, and their cells can be very small, and suitable for compact systems. Like BBO, LiNbO3 cells work in the transver mode. Please click here for more details.

In order to choose the right Pockels cells, the following factors should be considered:

1. what's the power density you want the cell to handle?

2. what's the repetition rate?

3. what's the beam size?

4. what's the desirable half (or quarter)-wave voltage?
