Abstract:
We present a brand-range self-sweeping Tm-Ho co-doped fiber laser experimentally. The laser's center wavelength sweeps periodically around 1.9 μm with self-sweeping range of 4 nm ~17 nm, and the sweep rate can be changed in the range of 0.4 nm/s ~1.5 nm/s. The sweep range increases and the sweep rate declines when the pump power rises.
