“…It is known that pulse shaping system based on two identical electrooptic deflectors provides the flexible pulse shape with power dynamic range of shaped pulse up to lO and high prepulse power contrast up to l08 [4]. This parameters is limited by light scattering on optical elements especially on imperfections of deflector crystals.…”

“…The characteristics of the shaping pulse depend strongly on the shape of the focal diaphragm in ASF3. The shape of this diaphragm is calculated for each required laser pulse shape, and its shape is ordinary as a drop [4].…”

“…By use of this facility the direct-drive fusion experiments have been performed for the spherical target illumination with shaped laser pulses in combination with the regular phase plates [3]. The shaped pulse is produced by the front end system based on the LiNbO3 electrooptic deflector [4]. After splitting the six beams are boosted up to 250 J per beam in 2 ns.…”

The design and performance of front end system for the upgrade six-channel Nd:glass laser facility PROGRESS are presented. The system consists of a single-mode Q-switch Nd:YLF master oscillator, pulse shaping system and preamplifier. The pulse shaping system comprises a LiTaO3 electrooptic deflector pair driven by high-voltage generators on drift step recovery diodes. The system produces the shaped laser pulses in 1-10 nanosecond duration range. In one-pass preamplifier including a sequence of Nd:glass rod amplifiers with output aperture of 30mm the shaped pulses are amplified up to 5 J energy level.
