Dynamic behavior caused by Brillouin scattering in Raman fiber amplifiers is studied. Modes of self-pulsation steady state oscillations are found. Their dependence on amplification scheme is demonstrated.
In this paper, we describe compact laser sources based on high-power amplification in Yb-doped silica fibers of ultra-stable mode-locked pulses from an all-fiber oscillator. The interplay between third-order nonlinearity, gain and chromatic dispersion in the polarization-maintaining fiber amplifier is engineered to produce high-quality, high-energy pulses suitable for nonlinear generation of light...
Experimental results obtained on 10 Gb/s RZ-DPSK transmission in a recirculating fiber-loop setup have shown that nonlinear amplifying loop mirrors (NALM) can efficiently enhance system performance: cascaded phase-preserving amplitude regeneration can efficiently prevent the accumulation of amplitude and nonlinear phase noise components in such systems. It was possible to significantly augment the...
Supercontinuum generation study in dual core square lattice photonic crystal fibre made of multicomponent glass was performed. The fiber was excited by 100 fs pulses of Ti:sapphire based optical parametric amplifier system with tunability range of 1100 - 1500 nm. Zero dispersion point of the relevant modes in the studied fiber is in area 1200 - 1300 nm, so there was a possibility to excite the fiber...
