In contrast to analogues, they can provide rapid switching of input voltage in two directions: both up and down. QBU-Series Pockels Cell Driver is extremely flexible solution for driving of the Pockels cell that works upon any user-defined scheme (that may be pull-up, pull-down schemes or any combinations of them). Modules provide wide range of output direct voltages (up to 6 kV). It allows operation with Pockels cells assembled on different electrooptical crystals from low quarter-wave voltage Lithium Niobate and BBO to DKDP that requires much higher voltage levels for proper operation. Moreover, QBU-Series modules provide high repetition rates (up to 100 kHz) that makes them a good solution for electro-optical Qswitched lasers with CW pumping.On the other hand a short rising (falling) time allows operation in short-pulsed systems with high peak output power and energy (flashlamppumped Nd:YAG lasers). Specification Input: Voltage Output: Voltage Repetition Rate Load Rise time (Fall time) Recovery Time Safety: Leakage Current Environment: Operation Temperature Storage Temperature Humidity Size (LxWxH) Weight Options +24VDC up to 6 kV from single pulse to 100 kHz up to 0.5 nF 20 ns 10 us (depends on load, @ 100 nF) not more than 150 uA -20…+45 C -40…+85 C 90%, non-condensing 130x80x20 mm 0.1 kg Harsh environment version Features Extremely flexible solution Pull-up and pull-down schemes Compact OEM design Up to 6 kV output voltage Up to 0.5 nF load Long cable operation Up to 100 kHz repetition rate Another advantage of QBD-series drivers is a ability of handling with extremely high loads (up to 0.5 nF). This feature leads to higher reliability of the device and permits remote operation of Pockels cell in laser head that can be connected to driver using long cables (correct and effective operation has been approved with cables up to 3 meters). This allows the designing of Q-switched laser systems with compact remote laser heads where close placement of Pockels cell and driver is impossible because of volume insufficiency or other causes.

Time of rapid pulse growth (20 ns) is indicated in red on figure; time of same rapid slump is indicated in blue (20 ns). Adjustable voltage level HV is designated by the arrow. How to order QBU-YYZZ Minimal output voltage: from 12 to 20 (1.2-2.0 kV) Maximal output voltage: from 20 to 50 (2-5 kV) We offer three standard solutions: QBU-5020 QBU-4016 QBU-3012 Application QBU-Series Pockels Cell Drivers are available in standard and special versions. Standard modification is a relatively simple OEM device designated for operation in laboratory or medical laser systems at normal temperature and humidity conditions. These modules are designed in accordance with IEC60601-1 medical safety standard requirements. Output parameters (direct high voltage) are controlled by use of analog interface. Special version is available for laser systems designated for operation in harsh environment. These devices are distinguished due to wide operation temperature range, humidity and vibration steadiness. In this version all parameters are controlled by simple and reliable internal multiturn trimpots. Other output voltages from 0.8 to 6 kV are available on request Working scheme HV Set (0-10V) TTL Input QBU-series Pockels cell driver HV output TTL input of almost arbitrary shape HV output follows TTL input with short rise/fall times HV 0
