Optical pulse compression using similariton propagation in an optical fibre with decreasing dispersion has been demonstrated for the first time. This scheme is a practical application of sech-similariton solution to generalized nonlinear schrodinger equation(NLSE) distributed coefficients recently found self similarity technique. The profile constructed comb-profile approximation technique and ...

A chip-based temporal compressor for shortening the duration of optical pulses has been developed by scientists in Japan. The scientists at Yokohama National University made their compressor from a silicon photonic crystal waveguide. Co-propagating slow light is used as a control pulse and serves to induce carrier plasma dispersion in the waveguide through two-photon absorption. The efficiency ...

Target recognition is the most challenging problem for missile defense. For accurate target recognition discriminant features must be extracted from the target signature. To extract suitable features an optimized waveform is needed which can be generated using pulse compression techniques. Pulse compression is a technique which can be generally used for achieving the benefits of short pulse rat...

the range imaging based on conventional pulse compression technique requires lfm signal that sampled by nyquist rate. in order to high resolution increased in range in pulse compression, so the lfm bandwidth has to increase. consequently this procedure dictated limitations on adc sampling. the stretch processing is one of techniques decreasing nyquist rate in radars. in this method the nature o...

High gradients require high peak powers. One possible way to generate high peak powers is to generate a relatively long pulse at a relatively low power and compress it into a shorter pulse with higher peak power. It is possible to compress before DC to RF conversion as is done for the relativistic klystron or after DC to RF conversion as is done with SLED. In this note only radio frequency puls...

Future linear colliders will require a very high peak power per meter of accelerating structure at a relatively high frequency-greater than 10 GHz-but at a relatively short pulse length-less than 100 ns. One technique for generating the required peak power is to use a more or less conventional microwave power source, which produces power at a pulse length typically on the order of 1 ps, togethe...
