On dipole source representation for laser-generated sound
conference contribution
posted on 2010-04-20, 11:36 authored by Victor V. KrylovIt is normally assumed that at the
thermo-optical regime of laser-generated ultrasound
in solids the equivalent thermo-optical source can be
modelled as a mechanical dipole comprising two
horizontal forces applied to the surface in opposite
directions. In the present paper this assumption is reexamined
on the basis of the rigorous theory that
takes into account all acoustical, optical and thermal
parameters of a solid material and all geometrical and
physical parameters of a laser beam. It is shown that
the dipole-source representation is rather limited,
especially in respect of generated longitudinal waves.
A general criterion has been established under which
the dipole-source representation gives predictions
with acceptable errors.
