International Conference on
Selective laser spectroscopy of solids: A history, fundamentals and applications
Michael Sapozhnikov
Lebedev Physics Institute, Russia
A
history of the development of selective laser
spectroscopy of solids is described, beginning from
a pioneering work by Yu. V. Denisov and V. A. Kizel in
1967, who were the first to demonstrate removing the
inhomogeneous broadening of luminescence spectra of
ions in glasses upon monochromatic resonance excitation.
Selective excitation of optical centers is achieved due
to existence of very narrow homogeneous zero-phonon
lines in the spectra of impurity centers in solids, which are
hidden in broad inhomogeneous optical bands upon usual
nonselective excitation. The fundamentals of zero-phonon
transition spectroscopy are considered and the mechanism
of removing the inhomogeneous broadening of optical
spectra of ions and molecules in crystals and amorphous
solids under selective laser excitation of luminescence and
persistent hole burning in absorption spectra is analyzed in
detail. Various applications of selective laser spectroscopy
for fundamental and applied studies are discussed.
