“…Volume holographic techniques are of particular interest for their spectral sensitivity and their capacity to achieve spatial as well as temporal modulation of UPB. Recent studies [1][2][3][4] have shown that by choosing proper grating parameters based on the coupled wave theory of Kogelnik [5], it is possible to achieve a large diffraction bandwidth for the readout UPB to be used for frequency-domain pulse shaping, which is applied to the one dimension volume gratings. The input and output boundaries are much larger than the grating thickness.…”

A detailed study of pulse shaping properties in crossed-beam volume gratings is performed. Analytical expressions for the profiles of the transmitted and diffracted beams are obtained based on the modified coupled wave theory. The spatial and spectrum evolutions and the diffraction efficiency of the diffracted pulsed beams are discussed. It is shown that the profiles of diffraction pulses and the total diffraction efficiency are greatly affected by the grating size, recording angle, and refractive-index modulation. The studies indicate that the shaping properties for different geometry parameters of the crossed-beam volume gratings are different. However, this difference can be used for many special pulse shaping applications.

“…The research on diffraction of ultrashort optical pulses by VHGs has recently attracted considerable attention. Ding [9] have shown both theoretically and experimentally that it is possible in frequency domain to achieve a large enough diffraction bandwidth of VHG for a bandwidth of 100fs pulses mainly by increasing the grating period and decreasing the grating thickness. Recently Wang [10] have studied the pulse shaping properties of a VHG read by an ultrashort pulse considering the combined effects of the grating parameters, the dispersion and optical anisotropy of the media and the polarization state of the incident light.…”

Volume gratings are of wide interest in many applications because of their properties of high diffraction efficiency, excellent wavelength selectivity and angular selectivity. Ultrashort pulsed laser has many promising applications in the fields such as optical communication, signal and imaging processing. Because of its abundant spectrum and wide bandwidth, the diffraction properties of volume gratings under illumination by ultrashort optical pulse will be different from that of a monochromatic continuous wave. A periodical structure is highly dispersive and such a dispersive property can be used to control the group velocity of light beams. So the spectral properties and dispersive properties of the periodically layered structures such as volume gratings when a linear chirped Gaussian pulse illuminated are very necessary. These properties can be applicable to addressable filter, switching, and controllable optical delay line. In this paper, a detailed study of linear chirped ultrashort pulsed beams diffracted by volume gratings in dispersive media is performed. The group delay characteristics of the diffraction spectrum of the transmitted and reflected volume gratings were studied based on the modified coupled wave theory. The analysis and observation of this paper will be valuable for the designing optical elements based on diffractive structure for the use with linear chirped ultra-short pulsed waves.

“…For the even shorter pulses, in which the above method is difficult to utilize, shaping them in the Fourier domain offers an alternative technique, where the optical frequency components of the UPB are spatially dispersed by a dispersive element, then modified by a filter, and recombined by an identical dispersive element to form the temporal output with a shaped waveform. Among many filtering masks for the UPBs, volume holographic gratings (VHGs) are interesting because of their flexibility and the possibility of using them to implement dynamic processing [6][7][8][9][10][11][12] . Y. Ding [7] et al have shown both theoretically and experimentally that in the frequency domain it is possible to achieve a large enough diffraction bandwidth of VHG for the bandwidth of 100-fs pulses mainly by increasing the grating period and decreasing the grating thickness.…”

A new technique for ultrashort pulsed beams (UPBs) shaping that uses volume holographic gratings (VHGs) recorded in anisotropic crystals by modulating the polarization states of the input UPBs is proposed and analyzed. Our approach is based on the investigation that when a VHG recorded in anisotropic crystals is illuminated by a UPB, the spectral and temporal widths and the shapes of the diffracted and transmitted pulsed beams vary with the polarization state of the input UPB, based on the extended coupled wave theory of Kogelnik which combines with the dispersion effect of the crystal materials. By using this approach, the modulation ranges of the spectral and temporal widths of the output UPB can be controlled by the parameters of the grating. Moreover, the diffraction efficiency of the volume holographic grating is analyzed, which also varies with the polarization state of the input UPB. An example of using this approach is given that a linearly polarized Gaussian-shaped UPB with duration of 30fs is effectively shaped with a transmission volume holographic grating recorded in photorefractive LiNbO 3 crystals.
