for precision Switching with low Jitter and perfect Pulse Shapes

The system normally is delivered with an optical head, HV-powersupply and timing-system. Any custom specification, i.e. optimized for any other Pockels cells than shown below or other voltages, can be delivered.

Patent applications pending: DE 10251888.2, EP 03025619.2, US 698464





General Specifications

max. operation Voltage  20.0 kV  *)
max. Reprate  3 MHz continuous, up to 40MHz in burst mode  *)
optical rise- and fall- time;  1.5 - 7 ns  *)
Pulse width  any
on / of - ratio  0 < 1
Jitter, Input to Output  < 200 ps
Trigger Input Impedance  50 Ohm
Trigger Input  3 - 10V, width > 50ns

  *) These specifications are mutually dependent, i.e. reprates of 1.6 MHz are achievable at switching voltages of 1.0kV, at 10kV reprate may be limited to about 30 or 40kHz, higher switching voltage tends to increase risetime. For a burst mode switch maximum average pulse frequency must be observed.
