At the interface between laser-plasma physics and photonics "Plasma optics" aims at manip-
ulating high intensity laser pulses by exploiting the optical properties of a plasma. Transient
plasma structures (or plasma photonic crystals, or gratings) present a ultrahigh damage thresh-
old that overcomes the limit of traditional solid-state optics and makes it possible to manipulate
and control ultra-short intense laser pulses[1].
Two kinds of gratings can be produced in a plasma by the beating of two transverse electro-
magnetic waves (laser beams). According to the nature of the particle motion, whether electron
(Raman) or ion (Brillouin) plasma waves, the properties of these structures differ in terms of
lifetime and light manipulation capabilities.
The possibility to generate ion plasma gratings and induce a controlled energy transfer is by
now well established [2]. At laser intensities as high as 1015 − 1016 W.cm−2 the characteristic
time-scales for the setup of these non-linear ion-like waves can easily attain a few hundred
femtoseconds and their lifetime can last several picoseconds.
We will review the progress in the realization and optimization of an ion grating (Stimulated
Brillouin Scattering) based amplifier, discuss the main limits that affect the energy transfer.
We will present recent results in the case of counter-propagating as well as co-propagating,
sub-picosecond beams at the same wavelength. We will discuss the role of laser and plasma
parameters in the interaction geometries.
