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:
FASTLITE
DAZZLER
crystal unit
RF Generator
Laptop computer
optical in optical out
SMA/SMA RF cable
USB link
synchro signal TTL
50 Ohm from Laser system
SMA/SMA RF cable 50 Ω
10 – 350 MHz 250 V

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 chapter 2. This unit is intended
to be inserted in the beam and will physically interact with it in order to pre or post compensate
