Drivers PCD-N-2 and PCD-N-3 are designed for Q-switching of nanosecond lasers without use of phase retardation plate. High voltage is applied to Pockels cell in order to inhibit oscillation. Pockels cell is opened by negative polarity pulse allowing laser to radiate. Driver need for external HV power supply, HV05Wm is suitable.
Drivers PCD-N-3D and PCD-N-3B is integrated with ±4 kV HV power supply. Voltage control is done using CAN interface. EKSPLA suggest CAN-USB converter with Can browser software for Windows® operating system. Can browser can be kept disconnected after proper voltage value was set.
Drivers PCD-N-2D and PCD-N-3D are designed for operation with DKDP crystals, drivers PCD-N-2B and PCD-N-3B – for BBO.
