摘要
文中使用熔融淬火法制备了氟化铝基、氟化铟基和氟化锆基玻璃样品,通过浸水实验研究了其抗潮解稳定性,结果表明氟化铝基玻璃具有更好的抗潮解性能。因此制备了不同浓度的Ho3+/Pr3+共掺氟化铝基玻璃样品,测试了其透过光谱,表明该玻璃具有高的透过率和宽的透过窗口。在1 150 nm拉曼激光的激发下,获得了样品的发射光谱,并对其发光机理进行了分析。利用吸注法制备了2 Ho3+/0.2 Pr3+掺杂的氟化铝基玻璃预制棒,使用棒管法拉制了氟化铝基玻璃光纤。使用回切法测得光纤在793 nm处的损耗为1.8 dB/m。在1 150 nm激光泵浦下,利用8.6 cm长的Ho3+/Pr3+共掺氟化铝基玻璃光纤作为增益介质,获得了功率为207 mW的2.865 μm激光输出,斜率效率为11.4%。上述研究结果表明,氟化铝基玻璃光纤是一种稳定的中红外激光增益材料。
Abstract
Fluoroaluminate, fluoroindate and fluorozirconate glass samples were prepared by using melt-quenching method, their abilities of resistance to deliquescence were studied by water treatment experiment, proving that the fluoroaluminate glass had better stability than the others. Thus Ho3+/Pr3+ codoped fluoroaluminate glasses with different concentrations were fabricated, the properties of spectral transmittance were measured, showing a high transmittance and wide transmission window. Under the pump of an 1150 nm Raman laser, the emission spectra were obtained for analyzing the emitting mechanism. 2 Ho3+/0.2 Pr3+ codoped fluoroaluminate glass preform were fabricated by suction method and fiber by rod-in-tube method. Using the cutback method, the loss of the fiber at 793 nm was 1.8 dB/m. By using the 1150 nm Raman laser as pump source, a 2.865 μm lasing with output power as high as 207 mW were detected in an 8.6 cm-long fluoroaluminate glass fiber, its slope efficiency was 11.4%. The above research results show that fluoroaluminate glass fiber is a gain medium material that can be used to develop stable mid-infrared fiber lasers.
