A Pockels cell alters the polarization state of light passing through it when an applied voltage induces birefringence changes in an electro-optic crystal such as DKDP (KD*P) and BBO. When used in conjunction with polarizers, these cells can function as optical switches, or laser Q-switches. Frequently, Q-switches are employed in laser cavities for the purpose of shortening the output pulse, resulting in a light beam with enhanced peak intensity. In order to provide the device best suited to your purpose, we offer the DKDP (KD*P) series and LiNbO3 series Pockels cell.
You can operate the cell with either a pull-up voltage or a pulldown voltage. Changing the polarity will only change the direction of the phase rotation. In other words, the pull-down voltage Q-switch use ª-/4-voltage pulses on the Pockels cell and the pull-up voltage Q-switch use ª-/2-voltage pulses on the Pockels cell. You should not, however, operate the cell with a constant applied voltage potential between the terminals, or a duty cycle greater than ~ 2%.

There are two kinds of E-O modulations. One is longitudinal E-O modulation if the directions of electric field and light propagation are the same. The KDP isomorphic crystals are normally used in this scheme. If the directions of electric field and light propagation are perpendicular, it is called transverse E-O modulation. The LiNbO3, MgO:LiNbO3, BBO and KTP crystals are usually employed in this scheme.

A water-cooled acousto-optic Q-Switch for use in high-power Nd:YAG laser systems. Combining top grade fused silica with high quality optical finishing and in-house anti-reflection coatings, this Q-Switch exhibits very low insertion loss and high damage threshold. Through an innovative design and manufacturing process, RF powers up to 100W may be applied. Standard options include a choice of frequencies (24 to 68MHz), active apertures (1 to 8mm), acoustic modes (compressional for linear polarisation, shear for unpolarised) and water connectors. Customised housings are available for OEMÆs.
A high power RF driver module is available in output powers of 50W, 75W or 100W. Powered from 220VAC or 110VAC, the modulation inputs allow either full digital control or activation of an internal pulse generator. First pulse suppression is automatically implemented.

The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratios (1.3-20 times) the Galilean telescope is most often employed due to its simplicity, small package size and low cost. * Material: BK7 fine annealed * Diameter: -0.1mm * Thickness: ¿¬+0.1mm * Flatness: l/4 * Surface Quality: 60-40 scratch-dig * Coating: HR dielectric coatings R > 99%.
