【摘要】：本文主要介紹了Yb3+離子摻雜雙包層光纖激光器。利用Matlab軟件對穩(wěn)態(tài)下速率方程進行了分析模擬。自行優(yōu)化設計了石英端帽,通過CO2光纖熔接機與光纖進行連接。實驗結(jié)果表明系統(tǒng)熔接端帽后明顯的改善了光纖的損傷閾值,有效的保護了光纖端面。搭建工作中心波長等于1080nm的鐿摻雜的雙包層光纖激光器,運用半導體激光二極管當作為泵浦源,諧振腔則由兩個光纖布拉格光柵構(gòu)成。其他實驗裝置還包括鐿摻雜雙包層光纖、合束器、包層泵浦剝除器、水冷等器件。當前已取得最大激光輸出功率等于123W,斜率效率等于62%,激光工作的中心波長為1080nm。
[Abstract]:This paper mainly introduces Yb3 ion doped double clad fiber laser. The rate equation under steady state is analyzed and simulated by Matlab software. The quartz end cap was designed by ourselves and connected with the fiber by CO2 fiber welding machine. The experimental results show that the damage threshold of the fiber is obviously improved after the end cap is fused, and the fiber end face is effectively protected. A ytterbium-doped double-clad fiber laser with a working center wavelength equal to 1080nm is constructed. The diode is used as the pump source and the resonator is composed of two fiber Bragg gratings. Other experimental devices include ytterbium-doped double-clad fiber, beam combiner, cladding pump stripping device, water cooling device and so on. At present, the maximum laser output power is equal to 123 W, the slope efficiency is equal to 62 and the central wavelength of the laser is 1080 nm.
