The Pockels cell is one of the most important optical components in laser systems, from a simple laser shutter to intensifying the output power density of lasers. The most common crystals for this Electro-optical application are DKDP, BBO, LiNbO3 and LiTaO3.
The cost-efficiency, easy adjustment and large-aperture availability make the DKDP Pockels cells the most ubiquitous since the invention of the laser. With several-decades of dedicated development, We 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 an exceptional EO material as well, especially for high power systems. Unlike the general DKDP Pockels cells, BBO Pockels cells work in the transverse mode, which means the actual half (or quarter)-wave voltage can be designed by changing the ratio of the aperture to the length. BBO Pockels cells can work in the systems with a high repetition rate.
LiTaO3, LiNbO3 and MgO:LiNbO3 crystals are not hygroscopic, and they can be used in low power systems. Their cells can be very small, and suitable for many compact systems. Like BBO, LiNbO3 cells also work in the transverse mode.
In order to choose the right Pockels cells, the following factors should be considered:
1. What is the power density you want the cell to handle?
2. What is the repetition rate?
3. What is the beam size?
4. What is the desirable half (or quarter)-wave voltage?
