KD*P Cells

CSATECH offer different kinds of KD*P Pockels Cells. The DPC-R series are cylindrical and the DPC-S series are cubic. For DPC-R series, the electrode connection can be optional among wires , thread and pin. And also, it's available with integrated, pre-adjusted Brewster polarizer such as DPC-R8S-PB and with ceramic to control the aperture such as DPC-R8S-PC.And for the DPC-S series, switching voltage can be halved such as DPC-S8D-P.

      CASTECH offer different kinds of KD*P Pockels Cells. The DPC-R series are cylindrical and the DPC-S series are cubic. For DPC-R series, the electrode connection can be optional among wires , thread  and pin. And also, it's available with integrated, pre-adjusted Brewster polarizer such as DPC-R8S-PB and with ceramic to control the aperture such as DPC-R8S-PC.And for the DPC-S series, switching voltage can be halved  such as DPC-S8D-P. All series Pockels Cells have AR coated windows for improved lifetime and protection in less user friendly environment.

 

Features:                                                 Applications:

◆ KD*P-based Pockels Cells                                            ◆ Medical and aesthetic laser systems

◆ Low absorption loss                                                        ◆ Cavity dumping

◆ Good temperature stability                                             ◆ Regenerative amplifiers

◆ High extinction ratio                                                         ◆ Q-switching of the laser cavity

◆ Capacitance value is small, fast switching speed

◆ High damage threshold

◆ Compact structure
