Ultrafast Electrical Pulse Generator

Calmar Laser's ultrafast electrical pulse generator (EPG) series provide pulse streams featuring broad range of pulse widths, high pulse amplitude, widely tunable repetition rates, low added timing jitter. The pulse generator can be triggered by an external random input and the pulses are locked to an RZ clock or sine wave input.

  • 10MHz ~ 5GHz repetition rate
  • 50~200ps pulsewidth
  • <1ps added timing jitter

EPG produces an electrical pulse stream with adjustable repetition rate from 10MHz to 5GHz. The output amplitude is typically 5V. The pulse width (FWHM) is selectable and/or tunable within 50~200ps. The added timing jitter is less than 1.0 picosecond.

In addition to be used as the electrical driver of high-speed laser diodes, EPG can also be used independently as a tool to calibrate and characterize ultrafast electrical components, modules, instruments and networks.
