Ultrashort soliton generation through higher-order soliton compression in a nonlinear optical loop mirror constructed from dispersion-decreasing fiber
A novel technique to generate ultrashort fundamental solitons is proposed and demonstrated numerically. The technique utilizes both the multisoliton pulse-compression effect and the switching characteristics of a nonlinear optical loop mirror constructed from dispersion-decreasing fiber. We show that, in contrast to the conventional soliton-effect pulse compression in which compressed pulses ar...
متن کاملAccurate modeling of high-repetition rate ultrashort pulse amplification in optical fibers
A numerical model for amplification of ultrashort pulses with high repetition rates in fiber amplifiers is presented. The pulse propagation is modeled by jointly solving the steady-state rate equations and the generalized nonlinear Schrödinger equation, which allows accurate treatment of nonlinear and dispersive effects whilst considering arbitrary spatial and spectral gain dependencies. Compar...

We have used a commercially available liquid-crystal spatial light modulator within a reflective optics pulse-shaping apparatus to shape ultrashort pulses with temporal resolution approaching 10 fs. Using the spatial light modulator as a phase modulator, we produce a variety of complex ultrafast waveforms, including odd pulses, high repetition rate (.23 THz) pulse trains, and asymmetric pulse t...
متن کاملHigh Energy/High Repetition Rate Laser Pulses from Yb Based Solid State Oscillators with Cavity-Dumping and Regenerative Amplifiers
Various scientific and industrial laser applications profit from the latest progress of directly diode pumped high-power femtosecond oscillators, in particular applications such as laser micromachining, nonlinear spectroscopy, or laser surgery. These oscillators provide pulse energies in the microjoule regime at 100 kHz to megahertz repetition rates, replacing complex and expensive chirpedpulse...
متن کاملPropagation of Parabolic Pulse through a Dispersion Decreasing Fiber with High Nonlinearity
Generation and propagation of Parabolic pulse through a designed and optimized silica based highly nonlinear dispersion decreasing fiber (HN-DDF) has been studied. It is seen that the proposed fiber can be treated as best choice for parabolic pulse generation with less input power requirement in comparison to standard normal dispersion fibers.
