摘要
采用管棒堆积法制作了芯径为25μm的Nd离子掺杂磷酸盐玻璃实芯光子晶体光纤(PCF),并测定了它的光学性能。用808 nm半导体激光端面抽运50 cm长的PCF。结果显示,与同组成的玻璃细棒相比,PCF在1060 nm附近的自发辐射放大(ASE)较强,而900 nm和1330 nm发光峰被抑制,同时1060 nm峰的线宽变窄。PCF在1060 nm的传输为单模,传输损耗为9.1 dB/m,这种PCF在光纤激光器领域有着潜在的应用前景。
Nd-doped phosphate glass photonic crystal fiber （PCF） with a 25 μm diameter core was prepared by the stack-and-draw method. Amplified spontaneous emission （ASE） spectra of the PCF were investigated by end pumping. The result showed that PCF has stronger peak at 1060 nm and dramatically weakened peaks at 900 nm and 1330 nm, while linewidth of the peak at 1060 nm gets narrower slightly than linewidth of glass rod. The single mode operation was obtained at 1060 nm with a measured loss of 9.1 dB/m. The potential advantages of application in the area of fiber laser were discussed.
