“…that may require different laser technologies with varying efficiency. For example, fiber lasers (coherently combined) are considered to be a candidate laser technology for high-peak and high-average laser power generation [21]. Using fiber lasers [22], higher efficiencies ($ 30%) are achieved near cw operation, while the efficiency drops significantly at lower (&10 kHz) repetition rates.…”

Beam-beam interaction constraints modify the basic plasma density scalings for a linear collider based on laser-plasma accelerators. In the quantum beamstrahlung regime, it is shown that operating at low plasma density increases beamstrahlung effects, owing to the higher bunch charge and longer bunch length. At high plasma density, the bunch charge is limited by beam loading, and the required power is proportional to the square root of the plasma density. At low plasma density, the bunch charge is limited by beamstrahlung, which, for fixed luminosity, requires operation at higher laser repetition rate and, hence, higher power requirements, or the use of multibunch trains. If round beams are used in a multibunch train format with fixed beam loading, and the collider is constrained by beamstrahlung, then the required collider power is independent of plasma density.

“…A new amplifying concept designed to produce high energy in either short or long pulses using coherent or incoherent addition of few millions fibres has been proposed in 2007 at the IFSA conference [2] and is currently explored by the Commissariat à l'Energie Atomique (CEA). It is clear that the fibre design looks really attractive from many different points of view: laser safety, operation and maintenance.…”

“…This third option features a very broad band amplification capability allowing a highly flexible short pulse generation (required for HiPER fast ignition scheme). Finally our fourth option (section 5) relies on the use of coherent/incoherent addition of a few million fibres as proposed in 2007 at the IFSA conference [2]. Such a design is attractive in terms of laser safety, operation and maintenance.…”

“…the superfluorescence source (SFS) and the superluminescent diode (SLD) source with no longitudinal modes but smoothly distributed photons within the spectral band is preferable for the applications of low coherence interferometry, optical coherence tomography (OCT), and optical gyroscopes [1][2][3]. Furthermore, the incoherent light may be a promising candidate for the inertial fusion driver, since it is helpful to reduce the Rayleigh Taylor (RT) hydrodynamic instabilities due to its smooth illumination in both time and space domain [4]. If the laser illumination of the imaging lidar is replaced by the incoherent light source, the imaging resolution could be further improved due to the speckle-noise-free feature of the incoherent light [5].…”

A phenomenological model for spectral broadening of incoherent light in silica fibers via self-phase modulation and dispersion is presented, aiming at providing a qualitative and readily accessible description of incoherent light spectral broadening. In this model, the incoherent light is approximated by a cosine power-modulated light with modulation parameters depending on the coherent time and the dispersion in fibers. A simple and practical method for spectral broadening predictions is given, and demonstrated by both the straightforward NLSE-based numerical modeling and series of experiments including narrowband and broadband incoherent light in passive fibers and fiber amplifiers.
