Electro Optical Components, Inc. Transverse Field Pockels Cells

Unlike the EM500 range of Pockels cells, the transverse field Pockels cells can be made in a more flexible range of sizes and in a greater choice of materials. The construction usually consists of either one Z-cut crystal in the case of lithium niobate, or two X or Y cut crystals, orientated for birefringence cancellation in the case of lithium tantalate. Other materials are available to suit special requirements, but none can match these for their established quality and low cost. For most applications, the designs can be mounted in a simple machined aluminum alloy channel housing of an appropriate size to match the crystal(s). If necessary, this may incorporate special fixing or other dimensional requirements at a moderate cost.
