Abstract
The technology of fast-pulsed lasers is developing at dramatic speed with
pulsed laser systems producing shorter pulses with higher repetition rates every
year. However, one problem comes with the advanced technology of fast
pulses -- the standard statistical optical theory is not sufficient to describe the
propagation and scattering of these pulsed fields. Statistical optics is based
on stationary, nondeterministic light, but very fast short pulses cannot be
modeled in stationarity. Such fields can still be interpreted as other type
of random process. My research is on the diffraction of random pulses from
arbitrary diffraction masks. I started with the diffraction pattern of the most
simple deterministic light, and then stationary light. Comparing the diffraction
patterns of these two with the diffraction of cyclostationary pulsed light,
I hope to have better insight into the fast short pulse train problem.
