Study on Writing and Reading of the Volume Grating by Time Domain Ultra-Short Pulse
时域超短脉冲光栅记录和读取的研究

In order to realize the reconstruction or the shaping of the ultra-short pulse,the writing and reading of the volume grating by ultra-short pulse in time domain are theoretically analyzed,and when pulse widths of signal wave,reference wave and reading light are different,the diffraction spectrum under Gaussian profile.Holography is put forward to realize the reconstruction or the shaping of the ultra-short pulse.It can be found that:when writing the holography with long signal pulse and short reference pulse,the signal pulse can be reconstructed totally if the reading pulse is short enough;while the width of diffraction spectrum decreases if the width of reading pulse approaches that of signal pulse.
