(i) Laser irradiation of materials with laser pulses whose energy density
is around the ablation limit, no matter whether they are femtosecond or
nanosecond pulses, do produce microconical structures despite of the, most
likely, different mechanisms involved. These structucture do have several
interesting applications.
(ii) We will show how a metalic thin film of nanoparticles can be rearranged
just by shining few laser pulses with a well defined intensity structure.
