LINOS Pockels CellsThe spectral window of BBO also ranges from0.25 μm to 1.3 μm. In addition, BBO crystals provide alow dielectric constant and a high damage threshold.Therefore, BBO is recommended for lasers with highrepetition rate and high average powers.cell will be determined by these factors. Thin filmpolarizers are used and the substrate is mounted atthe Brewster angle. A parallel beam displacementof 1 mm results from this configuration and can becompensated by adjusting the resonator.30RTP, with an optical bandwidth from 0.5 μm up to1.5 μm, combines low switching voltage and highlaser induced damage threshold. Together withits relative insensitivity for Piezo effects RTP is bestsuited for precise switching in high repetition ratelasers with super fast voltage drivers.For wavelengths from 1.5 μm up to 3 μm werecommend LiNbO 3.Suppression of Piezo effectsLike any other insulating material electro opticalcrystals show Piezo effects when high voltage isapplied. The extent of the Piezo ringing dependson the electro optic material and usually its effecton the extinction ratio is negligible when used forQ-switching. However, for pulse picking applications,which require highly precise switching behaviour,Qioptiq offers specially Piezo damped Pockels cellswhich suppress these ringing effects efficiently.State of PolarizationThe MIQS- and CIQS-series cells are supplied with anintegrated polarizer: the alignment of the Pockels cellrelative to the polarizer thus becomes unnecessary.The rotational position of the cell relative to theresonator axis can be chosen at will. However, shouldthe polarization state of the light in the resonator bedetermined by other components, such as anisotropicamplification of the laser crystal or Brewster surfacesof the laser rod, then the rotational position of the
