“…The resulting spectrogram provides the required information [17,18]. In a demonstrative experiment using an incoherent pulsed laser source at 620 nm [19,20], the phase correction due to a time reversing mirror has been analyzed with the help of SI. Starting with the equivalent of chirp-free sub-picosecond pulses, a dispersion line made of a grating pair stretched the pulses, making them chirped.…”

“…Optical coherent transient (OCT) techniques are not only well-established spectroscopic tools, but also the basis of a variety of proposed devices for optical information storage and processing [1][2][3][4][5][6][7]. To model the OCT processes, such as photon echoes, free induction decay and optical nutation, the coupled Maxwell-Bloch equations have been used successfully for the collinear configuration in thick media [9][10][11][12][13][14].…”

“…The propagation effects are governed by Maxwell's equations, where the macroscopic polarization caused by the atomic dipole moments acts as a source to the electric field. Recently, more complex configurations have been proposed to make practical OCT-based devices, such as pulse shaper and arbitrary waveform generator [5][6][7][8]. This kind of devices requires angled beam configurations to discriminate the processed signals from unwanted transmitted inputs.…”

“…Adaptation of the method to spectral-time holography for forming and processing ultrashort femtosecond pulses in the near-IR region (region of principal wavelengths for optical telecommunications), i.e., applicable to pulsed radiation from a titanium-sapphire laser [3][4][5], is especially interesting. The method is based on the fact that PSHB materials at very low temperatures have high spectral selectivity and are essentially frequency-selective storage devices.…”

“…Thus, a study of PSHB on Si-2,3-naphthalocyanine incorporated into polyvinylbutyral (PVB) with various additives showed that the hole-burning effectiveness could be increased with two-color irradiation, especially with added fullerene C 70 [4,8]. The phases of pulses with linear frequency modulation were monitored using t-butyl-substituted 2,3-naphthalocyanine incorporated into PVB [5]. It was reported that such a pulse or its fully time-inverted copy was reproduced and the use of PSHB materials in the new method was proposed for decompression of randomly time-distorted pulses.…”

Spectral and luminescent properties of recently synthesized compounds of a class of hydroporphyrazines, triarenotetraazachlorins, in polyvinylbutyral films have been studied. Fluorescence lifetimes have been measured in film and in solution. Fluorescence quantum yields have been estimated. It is found that annelation of aromatic rings to the pyrrole rings of the tetraazachlorin macrocycle enhances fluorescence. Quantum-chemical optimization of the geometrical structures of the free-base 1,2-trinaphthotetraazachlorins has been carried out using the AM1 method. The two isomers were shown to be highly non-planar. Spectral hole burning in absorption bands of both this compound and free-base 2,3-trinaphthotetraazachlorin in polyvinylbutyral films at 5 K in the wavelength region of titanium-sapphire laser radiation is possible and is ascribed to NH-photoisomerization.Introduction. Existing technology for amplifying femtosecond pulses that is based on their expansion and time compression before and after amplification encounters a serious problem with reproducing the time parameters of the amplified pulse (primarily the phases), which are distorted in the optical elements used in this method. Because femtosecond pulses cannot be programmed with time due to the lack of sufficiently fast modulators, as an alternative the programming can be done by changing the broad spectrum of the pulse. This should produce an equivalent result because the time and spectral coordinates are mutually interchangeable through a Fourier transform. The usual method for carrying out this procedure involves first dispersing the spectrum of the pulse with a diffraction grating in the focal plane of a lens in which a space modulator is placed (for example, a point liquid-crystalline modulus) in order to control separately and change the strength and/or phase of each frequency channel.An original approach to forming short (pico-and subpicosecond) pulses in which materials based on free bases of porphyrins that are capable of persistent spectral hole burning (PSHB) are used has been proposed [1,2]. Adaptation of the method to spectral-time holography for forming and processing ultrashort femtosecond pulses in the near-IR region (region of principal wavelengths for optical telecommunications), i.e., applicable to pulsed radiation from a titanium-sapphire laser [3][4][5], is especially interesting. The method is based on the fact that PSHB materials at very low temperatures have high spectral selectivity and are essentially frequency-selective storage devices. This means that they exhibit simultaneously properties of a spectrometer with very high resolution and a photographic plate or CCD camera. Therefore, any type of spectral information can be stored in them without needing to disperse the spectrum over a spatial coordinate. The time information contained in the spectral hologram recorded on the PSHB material can be read as an echo-signal arising from diffraction of the short reading pulse on the spectral lattice. Thus, the echo-signal carries info...
