High-energy pulse generation using Yb-doped Q-switched fiber laser based on single-walled carbon nanotubes
|
摘要
An all-fiber laser using a single-walled carbon nanotube(SWCNT) as the saturable absorber(SA) for Q-switched operation in the 1031 nm region is demonstrated in this work. A lasing threshold as low as 17 mW was realized for continuous wave operation. By further increasing the pump power, stable Q-switched pulse trains are obtained when the pump power ranges from 38 mW to 125 mW, corresponding to repetition rate varying from 40.84 kHz to 66.24 kHz, the pulse width from 2.0 μs to 1.0 μs,and the highest single pulse energy of 40.6 nJ respectively.
