An optical parametric amplification device, including: an emitter emitting non-monochromatic light pulses as a pump wave; a stretcher configured to receive as an input pump wave, and to output a stretched pump wave; and a waveguide configured to receive as an input the stretched pump wave and chirped pulses, and to provide a wave resulting from a four wave mixing.

Optical parametric ultrashort pulse amplifier

Method and device for the optical parametric chirped pulse amplification, using two pump signals and making it possible to extend the spectral gain band. According to the invention, which is particularly applicable to laser-matter interaction, a four-wave mixing effect is used, preferably in an optical fiber (F), between each pulse (S) and the two pump signals (P, P); and the half-sum (fM) of the respective optical frequencies (fP1, fP2) of these signals pertains to the pulse spectrum support.

Method and device for the optical parametric amplification of pulses with frequency drift

A microstructured optical fiber for generating broadband white light having a core doped with germanium and silica cladding surrounding the core, the cladding including a plurality of holes arranged in the form of a regular mesh, wherein the diameter F of a hole in the cladding, the pitch L between the respective centers of two neighboring holes in the cladding, and the refractive index difference Dn between the germanium-doped fiber core and the silica of the cladding are such that the fiber can generate white light on the fundamental mode over a wavelength band having a width of at least 1000 nm.

Microstructured optical fiber and a device for generating broadband white light

A system for generating polychromatic light, which includes: an optical pumping device suitable for continuously or quasi-continuously emitting a monochromatic or quasi-monochromatic radiation according to a pumping wavelength; a device for guiding light arranged such as to emit polychromatic radiation continuously or quasi continuously, at the output thereof, and a device for coupling between the pumping and coupling device. In the system, the guiding device, includes a microstructured optical fiber in which the core is at least partially doped with a material having a high intrinsic non-linear response, and the geometry of the optical fiber and the doping rate of the core thereof are predetermined such as to adapt the zero dispersion length of the optical fiber to the pumping wavelength.
