Resumo

We present laser action in a single crystal fluoride fiber obtained by the micro-pulling-down technique. The 700 mu m diameter and 1 cm long Nd:LiYF(4) fiber was pumped by a beam shaped diode bar emitting at 806 am. A peak power of 300 mW was achieved with a slope efficiency of 12%. When considering the pump power fraction absorbed by the laser mode, a slope efficiency of 37% was achieved. To the best of our knowledge, this is the first report of a Nd: LiYF(4) fiber laser.
