制备了镱铒共掺的磷酸盐玻璃并研究了室温下LD泵浦的连续激光输出性质.在泵浦功率为496 mW时实现了最大输出功率77 mW.讨论了在不同玻璃样品厚度和谐振腔长度时的斜率效率的变化以及在不同玻璃样品厚度,泵浦功率和谐振腔长度时的不同激光模式竞争的动力学行为.结果表明:激光光谱受到光学增益和光学损耗相对大小的限制.
Yb3+/Er3+ codoped phosphate glass was prepared and its laser properties at continuous wave(CW)pumped by LD were studied at room temperature.The maximum output power 77 mW was obtained at pumping power 496 mW.The slope efficiencies were discussed in different glass sample thickness and different resonance cavity length,and the competing dynamic behavior of various laser modes spectra were discussed in different glass sample thickness at the same pumping power,different pumping power and different resonance cavity length.It was found that the laser spectra were limited by the relative intensity of optical gain and optical loss.
