Paper Abstract

A twelve-channel system is described, intended for recording the laser radiation temporal parameters and dispersion on the ISKRA-5 laser facility. These measurements are needed for synchronous delivery of all twelve laser beams at the target with a minimal difference in the arrival time. The system uses a high-speed camera and fiber-optical communication lines (FOCL). Coupling of wide-aperture 720 mm beams into FOCL with a 50 micrometers aperture has been experimentally verified. The measuring channel sensitivity (10 (mu) J at the pulse width duration 0.5 ns and laser radiation wavelength 1.315 micrometers ) allows to use the recording system over the entire facility including initial amplification stages and master oscillator. It has been shown that it is possible to make complex measurements of the temporal shape and dispersion of laser beams from all channels of the facility with an error not exceeding 25 ps. As an illustration the recorded results obtained in experiments on ISKRA-5 are presented.
