Abstract. The
influence of displacement of the pump source with
respect to the crystal center on
the thermal behavior of the laser
crystal is studied analytically. We
consider the pump energy to be
deposited into the pump region which
has been slightly displaced with
respect to the crystal center. An
analytical expression for
temperature distribution for such
off-central diode-pumped laser is
investigated. The results are then
applied to the Nd\,:\,YAG and
Nd\,:\,YVO$_4$ laser crystals and
compared with the conventional
diode-pumped lasers. We showed that
in this special case, the
temperature distribution equation
in the off-central pumping convert
to the conventional central pump
scheme.
