Abstract

We demonstrated the usage of samarium oxide (Sm2O3) polymer film as a saturable absorber (SA) for generating stable Q-switched fibre laser at the C-band region. The SA was prepared by embedding a commercial Sm2O3 powder into polyvinyl alcohol (PVA) solution to form a Sm2O3-PVA film. The obtained film was then cut into a square shape of 1 mm x 1mm and adhered to the tip of fibre ferrule by using index matching gel. A stable Q-switching operation presence from 52 mW to 164 mW pump power at 1568 nm wavelength. Under this pump power, the repetition rate increased from 24.34 kHz to 55.80 kHz, while the pulse width reduced from 13.29 µs to 6.96 µs. The obtained Q-switching operation has a signal-to-noise ratio (SNR) of 38 dB with a maximum output power and pulse energy of 8.58 mW and 123.27 nJ, respectively. This finding shows that the Sm2O3 has good potential to be used as an alternative passive SA for the C-band all-fibre laser seed pulse.
