摘要
利用铥离子掺杂氟碲酸盐玻璃光纤作为增益介质,采用1400/1570 nm双波长激光作为泵浦源,建立了2.3μm光纤激光器理论模型。通过数值求解,系统研究了增益光纤长度、损耗、泵浦光功率等对2.3μm激光性能参数的影响。仿真结果表明,当掺铥氟碲酸盐玻璃光纤长度为2.3 m、1400 nm泵浦光功率为30 W、1570 nm泵浦光功率为2.4 W时,获得的2.3μm激光功率可达14.7 W,相应的转换效率为45.37%。该研究可为研制高功率2.3μm掺铥光纤激光器提供理论指导。
This study employed a thulium-doped fluorotellurite glass fiber as the gain medium and utilized dualwavelength lasers at 1400 nm and 1570 nm as the pump sources to establish a theoretical model of a 2.3μm fiber laser.Through numerical simulations,the effects of the gain fiber length,fiber loss,and pump power on the performance parameters of the 2.3μm laser were systematically investigated.The simulation results showed that when the length of the thulium-doped fluorotellurite glass fiber was 2.3 m,the pump power at 1400 nm was 30 W,and the pump power at 1570 nm was 2.4 W,the output power of the 2.3μm laser reached 14.7 W,with a corresponding conversion efficiency of 45.37%.This research provides theoretical guidance for the development of high-power 2.3μm thulium-doped fiber lasers.
