FABRICATION AND PROPERTIES OF Nd3+ DOPED FLUOROZIRCONATE GLASS FIBER

研究了掺Ｎｄ３＋氟锆酸盐玻璃光纤的制备方法，获得Ｎｄ３＋浓度为１×１０－３，芯径为９μｍ，外径为２００μｍ的双层玻璃包皮的氟锆酸盐玻璃光纤．在利用一个Ｆａｂｒｙ－Ｐｅｒｏｔ腔和５１４ｎｍ氩离子激光器作光泵源组成的光纤激光器中，室温下已获得１．０５μｍ连续激光输出，输出功率为１１ｍＷ，斜率效率２０％．在信号源波长为１．３２７μｍ的半导体激光器和光泵波长为８００ｎｍ的钛宝石激光器组成的放大器上，获得８．５ｄＢ的增益．

The fabrication method of Nd3+_doped fluorozirconate glass fiber was studied. The fluorozirconate glass fiber with Nd3+ concentration of 1×10-3, a core diameter of 9μm, outside diameter of 200μm and a double layer cladding glass was obtained. The laser properties of the fiber were measured using a Fabry-Perot cavity by pumping of 514 nm Ar laser. 1.05μm CW laser with output of 11 mW and slope efficiency of 20% at room temperature was obtained. The amplification performance of the fiber was measured using a 1.327 μm laser diode as signal source by pumping of 800 nm Ti:Sappphire laser. The signal of 8.5 dB was obtained.
