International audience; We propose a new, simple approach to enhance the spectral compression process arising from nonlinear pulse propagation in an optical fibre. We numerically show that an additional sinusoidal temporal phase modulation of the pul

We propose a new, spectral-interferometric, technique of complete characterization of ultrashort pulses. The technique is based on employing, as a reference, a sub-parabolic pulse with a known phase formed in a single-mode fiber from the pulse under

We propose and test experimentally a method, alternative to the autocorrelation technique, for determination of the duration of femtosecond laser pulses. The method is based on generation of nonlinear-dispersive similariton in a passive optical fiber

Applications of spectral compression - temporal lensing to signal analysis-synthesis problems in ultrafast optics

Autor: L. Kh. Mouradian

Publikováno v: 2008 4th International Conference on Advanced Optoelectronics and Lasers.

The concept of spectral compression - temporal lensing by self-, cross- and inter-phase modulation versions, and its applications to signal control and characterization in ultrafast optics with relevant experiments are presented. A special issue of d

Spectral compression of picosecond pulses by means of cross-phase modulation

Publikováno v: The 13th international conference on laser interactions and related plasma phenomena.

We develop a modified spectral compressor based on the process of cross-phase modulation (XPM), to implement the nonlinear- optic process of Fourier transformation. The proposed and probated nonlinear- optic Fourier transformer reproduces the field o
