The behaviour of the temporal Talbot effect under carrier partial coherence is analysed. This effect finds application as a passive method for multiplying the repetition rate of the intensity of pulse trains in first-order dispersive media. The study is based on the representation of the average ...
Thus the Talbot effect may help in the study of the temporal and spectral characteristics of ultrashort laser pulses. An experiment with an LED is given, as well. 展开 关键词: Coherence Diffraction gratings Gratings Diffraction theory Ultrafast technology ...
Figure 1illustrates the concept of our passive amplification technique. We effectively exploit an ‘inverse temporal Talbot effect’ in which the final amplified temporal image is recovered from a previous multiplied self-image. As shown inFig. 1, top, in the standard temporal Talbot effect, a fl...

Materials and Methods Image sensors. Live-cell populations were imaged using colour (Bayer filter array) and monochrome ICX098 Charge-Coupled Devices (CCDs) from Sony (Japan) driven by a remote-control electronic board Fire-i from Unibrain (Athens, Greece). The CCD array is composed of ...
Thus, the field of magnonics is well suited for the implementation of wave-based computing devices, combining the excellent versatility, smallness, nonlinearity and external control it affords. Novel coherent states of matter, such as magnon Bose–Einstein condensates, enable a broad range of ...
Coherent combining of light from multiple high power fiber amplifiers is a promising pathway to scaling the output power to hundreds of kiloWatts. In the last decade, substantial progress has been made in terms of scaling number of elements along with improvement in phase control techniques to ach...
The temporal Talbot effect is a well-established passive, coherent and all-optical technique for multiplying the repetition rate of the intensity of pulse trains in guided media after first-order dispersive propagation. In this paper we report on a matrix analysis of this technique under partial ...
