Abstract.
We investigated errors arising in calculations of optical signals in non-linear
laser spectroscopy due to neglection of non-uniformity in cross-beam laser
power distribution. The following three cases of non-linear emission are
considered: saturated molecular luminescence, sequential multi-photon
excitation of luminescence, laser-induced incandescence of micro-particles.
Keywords: non-uniformity
of laser power spatial distribution, non-linear processes, luminescence,
laser-induced incandescence.
