Ultrafast optical pulse shaping: A tutorial review
TL;DR: In this paper, a tutorial on the field of femtosecond pulse shaping, a technology that enables generation of nearly arbitrary, user defined, ultrafast optical waveforms, with control of phase, amplitude, and polari-zation, is presented.

Raman response function of silica-core fibers
TL;DR: In this article, the authors developed the Raman response function for silica-core fibers and used it to study the effect of Raman gain in regimes of normal and anomalous dispersion.

Generating coherent THz phonons with light pulses
TL;DR: In this paper, the authors present an overview of femtosecond-pulse generation of coherent optical phonons, focusing on Raman mechanisms for the coherent driving force providing a comprehensive approach for the description of both below-gap and resonant excitation.
Journal ArticleDOI
Impulsive stimulated scattering: General importance in femtosecond laser pulse interactions with matter, and spectroscopic applications
TL;DR: In this article, it was shown that "impulsive" stimulated Raman scattering (ISRS) should occur, with no laser intensity threshold, when a sufficiently short laser pulse passes through many types of matter.
Journal ArticleDOI
Femtosecond Pulse Sequences Used for Optical Manipulation of Molecular Motion
TL;DR: Optical control over elementary molecular motion is enhanced with timed sequences of femtosecond pulses produced by pulse-shaping techniques, analogous to repetitively pushing a child on a swing with appropriate timing to build up a large oscillation amplitude.

Crystal stability and the theory of ferroelectricity
TL;DR: In this article, it is shown that the parameters which determine the lattice vibrations of a diatomic ionic crystal may be chosen in such a way that the crystal will exhibit ferroelectric properties, and that anti-ferroelectric transitions may be regarded as the result of an instability of the crystal for a certain normal mode of vibration.
