In order to smooth the focal spot of high-power energetic lasers, pulses are phase-modulated. However, due to propagation impairments, phase modulation is partly converted into power modulation. This is called frequency modulation to amplitude modula

Within Neodymium doped laser crystals, the doping of fluorite-type single crystals reveals an unique possibility for broadband, high-energy, short-pulse laser amplification at 1µm, which makes these materials appealing to various high energy laser a

High-power nanosecond laser pulses are usually spectrally broadened via temporal phase modulations to tackle the issue of stimulated Brillouin scattering and to achieve optical smoothing of the focal spot. While propagating along the beamline, such p

Optical smoothing techniques are crucial for achieving well-controlled experiments at large-scale laser facilities dedicated to high-energy-density physics. Due to detrimental effects in the laser chain, however, those techniques can convert phase mo

Optical smoothing techniques are widely used in large high-power laser facilities designed for inertial confinement fusion research, such as the Laser Mégajoule (LMJ) in France. Those techniques are of primordial interest because they reduce laser

Forward pump pulses with nanosecond duration are able to generate an acoustic wave via electrostriction through a few centimeters of bulk silica. Part of the incident energy is then scattered back on this sound wave, creating a backward Stokes pulse.
