Recording of the Temporal Profile of the Laser Pulse Front at the Luch Facility with a Large Dynamic Range and Picosecond Resolution

The power contrast of the laser pulse is measured by recording the pulse front profile with a large dynamic range at the Luch facility using a fast photochronograph and fiber-optic communication lines. The power contrast of the laser pulse is 105. A way to increase the dynamic range of the method to 1011 is shown.
