基于掺铒氟化物光纤的2.8μm可调谐激光输出
Mid-infrared 2.8 μm tunable lasing based on erbium-doped fluoride fiber
摘要
Abstract
Heavily erbium-doped fluoride fiber is used to enhance the process of energy transfer up-conversion between erbium ions,leading to the generation of mid-infrared lasing around 2.8 μm.The full-band emission covering all the emitting lines of erbium ion from 0.5 μm to 3.0 μm is observed,and the emitting wavelengths agree well with the transitions between the corresponding energy levels.The full band lasing output of erbium ion is experimentally studied.It is found that 2.8 μm lasing is dominant due to the high doping level.With the pump power changing from 2 W to 4 W,the peak wavelength of 2.8 μm lasing could be tuned in the range of 2714-2784 nm,which is caused by the gain competition combined with the selectivity of cavity and the effect of inhomogeneous broadening.With the pump power increasing above 3 W,the spectral splitting of lasing can be observed.The high stable mid-infrared lasing at 2.8 μm is obtained with the maximum output power of 0.7 W and slope efficiency of~12%.关键词
