Introduction
1.1
System components
The DAZZLER system is an acousto-optic programmable dispersive filter. It enables to control
separately both spectral amplitude and spectral phase. The DAZZLER system is composed of
three main parts:

1.1.1
Crystal unit
The crystal is an active component which through the acousto-optic interaction allows to shape
the spectral phase and amplitude of an optical pulse.
The theory and performance of this interaction are described in
. This unit is intended
to be inserted in the beam and will physically interact with it in order to pre or post compensate
