TL;DR: In this article, an analytical expression for the propagation of the amplitude of tilted ultrashort pulses is derived and the conditions to be met in order to avoid such distortions arising are the pulse broadening, tilt angle decrease, chirp, frequency shift and spatial profile variation.

TL;DR: In this paper, a new technique called picosecond interferometry is proposed for the study of phonons in the Brillouin frequency range in transparent materials, which makes possible the measurement of longitudinal phonon velocity and attenuation under conditions such that the conventional approach is not applicable.

TL;DR: In this paper, a variation of electronic speckle pattern interferometry (ESPI) is presented whereby phase fringes are produced in contrast to speckles correlation fringes.

TL;DR: In this article, it was shown that the absorptance of thin films is nearly proportional to their transmittance, and that their ratio is virtually free of interference fringes, and can be used accurately to obtain the absorption coefficient of the film.

TL;DR: In this paper, it was shown that a sudden frequency change of a quantum oscillator e.g. during a Franck-Condon transition leads to squeezing and the characteristic function and the density operator of this squeezed state were constructed.

TL;DR: In this article, an XeCl pumped dye laser amplifier was used to amplify 70 fs pulses to an output power 7 GW at repetition rates from single shot to 100 Hz, where near diffraction limited and transform limited pulses are produced.

TL;DR: In this article, a new theorem was derived from which a number of previously known results relating to non-radiating monochromatic sources readily follow, and explicit expressions for the field within homogeneous spherical sources and curves are presented which show the behavior of the field in several nonradiating sources.

TL;DR: In this paper, a phase operator formalism is used to study the fluctuation properties of squeezed states and Variances in phase operators are calculated and used to construct number-phase uncertainty relations.

TL;DR: By feeding the output from a semiconductor laser back onto its own output facet with an appropriate delay, the oscillation was able to be brought into a chaotic regime as mentioned in this paper, and the dimensionality test of the waveforms gave a strong evidence that the observed waveforms were chaos.

TL;DR: In this paper, a simple and sensitive method for determining the birefringence of a BaTiO 3 crystal over the entire range of wavelengths where the sample is photorefractive was proposed.

TL;DR: In this paper, the effect of chirp and phase noise on the formation of solitons in optical fibres is examined. And the results show that the soliton are stable with respect to quite large effects of both chirps and phase noises.

TL;DR: The nonlinear phase shift, unavoidably induced in an electromagnetic field circulating in a fiber-optic passive-loop resonator by the presence of the optical Kerr effect, gives rise to a multistable behavior of the input-output characteristics at relatively low optical powers as discussed by the authors.

TL;DR: In this article, a two-step method is described to produce off-axis holographic lenses with high diffraction efficiency and without astigmatism for semiconductor lasers, where the hologram is recorded in the visible (514 nm) and reconstructed in the infrared (800 nm).
