  The purpose of the given message - interpretation of the processes providing
a photoluminescence and laser generation in spectral area 2000 nm at use as the
active laser environment cristall or glass material, activated by an
atomicholmium. Offered in article interpretation is based on use of the law of
the conservation of energy, which attraction allows to reveal in an atomic
holmium the transitions responsible for a photoluminecsence in specified area
of a spectrum (2000 nm).
