当电压施加到BBO电光晶体的电极时，BBO普克尔斯盒是用来改变通过它的光的偏振状态。常规的应用包括激光腔的调Q、激光腔倒空和耦合光的形成再生放大器。低压电振铃使得BBO普克尔斯盒对高功率、高重复频率激光器的控制具有很大的吸引力。快速开关电子驱动器适当匹配的电池可用于q开关，腔倾倒和其他应用。 BBO普克尔斯盒是横向场器件。四分之一波电压与电极间距和晶体长度的比值成正比，因此孔径较小，四分之一波电压较低，双晶设计具有较低的四分之一波电压，广泛应用于开关时间快的半波工作模式。. BBO-based pockels cell are used to change the polarization state of light passing through it when an voltage is applied to the electrodes of BBO electro-optic crystals.Typical applications include Q-switching of the laser cavity, laser cavity dumping and coupling light into and form regenerations amplifiers.Low piezoelectric ringing makes BBO Pockels cell attractive for the control of high-power and high repetition rate lasers. Fast switching electronic drivers properly matched to the cell are available for Q-switching, cavity dumping and other applications. BBO Pockels cells are transverse field devices.The quarter-wave voltage is proportional to the ratio of electrode spacing and crystal length, therefor, smaller aperture, lower quarter-wave voltage,besides,double crystal design,which has lowerquarter-wave voltage, is widely used to work in half-wave mode with fast switching times.
