Main components, included in standard:
  • Streak camera;
  • Femtosecond laser;
  • electro-optical modulator;
  • Fabry-Perot interferometer;
  • fiber optic stretcher.

The standard was developed in the interests of laser-optical instrumentation enterprises. It is used for testing, verification, calibration of instruments for measuring the temporal characteristics of laser pulses.
