Phase recovery by using optical fiber dispersion and pulse pre-stretching
Get PDFIn this work, the applicability of a recently proposed phase recovery technique is extended, by using temporal pulse pre-stretching. As a proof of concept, the light pulses emitted by a two-stage laser system consisting of a sub-picosecond passively mode-locked fiber laser followed by an erbium-doped fiber amplifier were experimentally analyzed. These results were successfully compared with two indirect phase recovery techniques, both based on the Gerchberg–Saxton recursive algorithm and with the intensity autocorrelation when sub-picosecond light pulses were analyzed.Fil: Cuadrado Laborde, Christian Ariel.

Functionalized Gold Nanoparticles as an Approach to the Direct ColorimetricDetection of DCNP Nerve Agent Simulant
No full text[EN] New functionalized gold nanoparticles have been synthesized and their ability to act as colorimetric molecular probes for the naked-eye detection of nerve agent simulant DCNP has been studied. The detection process is based on the compensation of charges at the surfaces of the functionalized AuNPs, which triggers their aggregation with the resulting change in the color of the solution.The authors thank the Spanish Government (grant numbers MAT2009-14564-C04-03 and MAT2012-38429-C04-02) and the Generalitat Valenciana (Project PROMETEO/2009/095) for support.

Comprehensive Theoretical and Experimental Study of Short- and Long-Term Stability in a Passively Mode-Locked Solitonic Fiber Laser
Get PDFWe demonstrate the short- and long-term stable operation of an all-polarization-maintained Fabry-Pérot cavity passively mode-locked fiber laser. The laser operates in an all-anomalous-dispersion solitonic regime. Laser stability is studied by a variety of measurements, which confirm the high stability of the laser in the temporal and spectral-both optical and electrical-domains. Pulse durations of 540 fs, period-relative time jitters of ∼0.015%, and long-term uninterrumped operation with 0.4% variation (standard deviation) in the average output power are obtained. The highly stable operation of the laser oscillator was maintained after amplifying the laser output with a conventional EDFA. Pulse durations of ∼244 fs, period-relative time jitters of ∼0.019%, and an average output power of 20 mW were obtained after amplification, while maintaining the 100-dB signal-to-noise ratio of the laser oscillator measured at 500-Hz offset from the fundamental harmonic frequency. The theoretical validation of our experimental results is based on solutions of the Nonlinear Schrödinger Equation. We demonstrate that wavelength and z -position dependences of the active medium gain must be taken into account for an accurate correspondence with the experimental properties of the laser.</p
