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.
