Communication systems that transmit data over bandlimited channels usually implement pulse shaping to avoid interference caused by the bandwidth limitation.
22.
Laser pulse shapes are customizable to circular, elliptical, square, and other profiles to provide the most convenient and efficient processing conditions.
23.
The steps which should follow to compute the pulse shape response for a given interaction position in the detector volume are:
24.
For ultrashort pulse lasers, a hyperbolic-secant-squared ( sech 2 ) pulse shape is often assumed, giving a time-bandwidth product of 0.315.
25.
New simulations considered the timing of the energy delivered in the pulse, known as " pulse shaping ", leading to better implosion.
26.
Taylor and Weisberg also mapped the pulsar's two-dimensional beam structure using the fact that the system's precession leads to varying pulse shapes.
27.
The purpose of matched filters is to maximise the signal-to-noise ratio ( S / N ) at the expense of pulse shape.
28.
This property allows obtaining very good efficiency of the XPW generation process with minimum distortions of the pulse shape and the spectrum.
29.
Sender side pulse shaping is often combined with a receiver side matched filter to achieve optimum tolerance for noise in the system.

LCoS was initially developed for projection televisions but is now used for wavelength selective switching, structured illumination, near-eye displays and optical pulse shaping.
