This research is oriented to laser generation by using rare earth
doped optical fibers as the active material. The Laboratory has
discovered the first Nd doped ultraviolet fiber laser. Also this
laboratory has the record for an ultra low threshold, laser
diode-pumped green fiber laser. Spectroscopy of Pr, Yb and Tm has also
been extensively studied, as well as generation of short pulses by
Q-switching. In general, the fiber lasers are several orders of
magnitude more efficient than conventional lasers, can be pumped by
laser diodes and can easily operate in a single spatial mode. For these
reasons fiber lasers can be considered as compact solid state lasers of
high efficiency and good beam quality. Our laboratory is focused mainly
in visible lasers because this region offers several challenges to the
conventional systems. Recent research in up-conversion fiber lasers has
demonstrated superiority over the conventional lasers in the development
of blue-green sources. Principle applications include laser
spectroscopy, medicine, laser displays, undersea communication, and high
density data storage.
Other lasers discovered in this laboratory include the CdI, CdBr, and
ZnI molecular lasers in the visible and near-IR.
