Chirped-pulse-amplification circuits for fiber amplifiers, based on chirped-period quasi-phase-matching gratings.
A new type of compact chirped-pulse-amplification circuit for high-power amplification of femtosecond pulses in an optical fiber is demonstrated. This circuit is based on a novel pulse compressor, chirped-period quasi-phase-matching gratings in electric-field-poled lithium niobate. The main advantages of this circuit are simplicity, the small number of components, compactness, and wavelength co...
متن کاملFiber optical parametric chirped-pulse amplification in the femtosecond regime.
We study parametric amplification in optical fibers for chirped-pulse femtosecond laser systems. Compared to conventional OPCPA operating in bulk crystals, the fiber geometry offers a greater interaction length and spatial confinement, an increased flexibility in the choice of wavelengths for signal and pump beams, and the robustness of fiber setups. As opposed to rare-earth doped fibers, param...
متن کاملSpatiotemporal noise characterization for chirped-pulse amplification systems
Optical noise, the core of the pulse-contrast challenge for ultra-high peak power femtosecond lasers, exhibits spatiotemporal (ST) coupling induced by angular dispersion. Full characterization of such ST noise requires two-dimensional measurements in the ST domain. Thus far, all noise measurements have been made only in the temporal domain. Here we report the experimental characterization of th...
متن کاملChirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system OPTICS COMMUNICATIONS
As in bulk amplifiers, the onset of nonlinear effects when amplifying ultra-short pulses in fiber amplifiers has been pointed out and investigated by several groups, specifically in erbium-doped fiber amplifiers ( EDFAs) [ l-3 1. Researchers have in fact used the Kerr nonlinearity in conjunction with group velocity dispersion in order to create even shorter pulses via higher-order soliton forma...
متن کاملChirped pulse amplification at VISA-FEL
Chirped beam manipulations are of the great interest to the FEL (Free Electron Laser) community as potential means of obtaining ultra short X-ray pulses. The experiment is under way at the ATF (Accelerator Test Facility) at BNL (Brookhaven National Laboratory) to study the FEL process limits with the under-compressed chirped electron beam. High gain near-saturation SASE operation was achieved w...
