DQF POCKELS CELL DRIVER FOR Q-SWITCHING FOR FLASHLAMP PUMPED LASERS
DQF series drivers are designed for Q-switching of nanosecond flashlamp pumped lasers without use of phase retardation plates. 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 DFQ-0.2-5D needs an external HV power supply, PS-5 model is recommended.
Driver DFQ-0.1-8D is integrated with 4 kV HV power suppliy. High voltage can be controlled either by onboard trimmer potentiometer or by using CAN interface. We suggest CAN-USB converter with CAN browser software for Windows operating system. CAN browser can be kept disconnected after proper voltage value is set.
