We report on a mid-infrared fiber laser that uses a single-walled carbon nanotube saturable absorber mirror to realize the mode-locking operation.The laser generates 3.5 μm ultra-short pulses from an erbium-doped fluoride fiber by utilizing a dual-wavelength pumping scheme.Stable mode-locking is achieved at the 3.5 μm band with a repetition rate of 25.2 MHz.The maximum average power acquired from the laser in the mode-locking regime is 25 mW.The experimental results indi-cate that the carbon nanotube is an effective saturable absorber for mode-locking in the mid-infrared spectral region.

As a universal phenomenon in nonlinear optical systems,intermittency is usually accompanied by the coherence loss such as soliton explosions in fiber lasers.Based on real-time spectroscopy,we revealed the coherent dissipative soliton inter-mittency in nor
We demonstrate a multi-channel pseudo-random coding single-photon ranging system.A pseudo-random multiplexing technique is proposed,which realizes multi-channel pseudo-random ranging only by using one single-photon detector and processing circuit.Compared
建立“结构+质量+创新+环境”解释框架,以长江经济带35个老工业基地城市为研究案例,运用定性比较分析方法,探讨影响老工业基地城市产业转型升级的条件组合.研究发现:长江经济带老工业基地城市产业转型升级有两类解释路径,一是以强质量提升为核心,二是强结构优化、强产业创新和强环境友好的组合.长江中上游老工业基地城市有更加多元的产业转型升级条件组合,质量提升与产业创新的组合则是长江下游老工业基地城市产业转型升级的重要路径.定性比较分析了长江经济带老工业基地城市产业转型升级的内在逻辑,以期有助于长江经济带及其他地区城
