29 February 2012Oxide crystal-fibers grown by micro-pulling-down technique and applications for lasers and scintillators
We demonstrated growth of YAG, LuAG and CALGO single crystal fibers with doping Nd, Yb, Er, and Ce by the
micro-pulling-down technique. Those fibers have applications in high power lasers and scintillating detectors. For laser
operation, average power of 65 W energy of 4 mJ and peak power above 7 MW have been demonstrated in various
configurations. Those results push the limits of end-pumped bulk crystals in terms of average power and exceed the
limits of pulsed fibers lasers in terms of energy. For scintillating applications, high density/high light yield detectors are
developed for nuclear science and medical applications.
