- W2808978916 abstract "This report presents two Q-switched Erbium-doped fiber lasers (EDFLs)utilizing topology insulators (TI) as saturable absorber (SA). The SA was fabricated byembedding Bismuth (III) Selenide (Bi2Se3) or Bismuth (III) Telluride (Bi2Te3) into apolyvinyl alcohol (PVA) film. The first Q-switched EDFL was obtained byincorporating a Bi2Se3 film inside the laser cavity. The laser generates stable pulse trainby changing the pump power from 86.1 mW to 116.6 mW with repetition rate that canbe tuned from 84.08 kHz to 87.03 kHz. It operated at 1559.8 nm wavelength with anexcellent stability. The RF spectrum showed the signal noise to ratio of about 60 dB.The maximum pulse energy of 36.9 nJ and the lowest pulse width of 5.11 μs wereobtained at pump power of 116.6 mW. The second Q-switched EDFL was demonstratedusing TI Bi2Te3 material. The laser operates at 1558.5 nm with a lower threshold pumppower of 25.0 mW. The repetition rate of the laser varies from 38.76 kHz to 77.88 kHzas the 980-nm pump power increased from 25.0 mW to 106.4 mW. The Q-switchingoperating has the shortest pulse width of 6.56 μs, the maximum pulse energy up to 127nJ and the peak-to-pedestal ratio of 65 dB for the RF spectrum. These results shows thatBi2Te3 film performed better than Bi2Se3 one in terms of pulse energy and wider tuningrange for repetition rate and pulse width. The experimental results also verify that bothTI films possess the potential advantage for stable Q-switched pulse generation at 1.5μm." @default.
