Abstract: | The spectroscopy properties of Nd3+ doped polymer fiber with 532 nm pumping radiation is studied. It is found that the emission peak near 580 nm is attributed the transition from 2G7/2 and 4G5/2 to ground level 4I9/2,and the florescence intensity of Nd3+ doped polymer fiber with 70 ppm concentration and 650 μm cord diameter increases as the fiber is shortened from 89 cm to 15 cm and decreases again for further shortening to 8 cm. Both the advantages and disadvantages of Nd3+ doped polymer fiber compared with Rhodamine B doped polymer fiber are discussed. |
