Abstract

A Q-switched erbium-doped fibre laser (EDFL) was successfully exhibited using gadolinium oxide (Gd2O3) as a saturable absorber (SA). The polyvinyl alcohol (PVA) solution and Gd2O3 powder were combined and the combination was then sonicated for around 6 hours. A micro-film was created by allowing the solution to dry out over the period of 48 hours. The Gd2O3-SA was inserted into an EDFL configuration to produce a steady passively Q-switched pulse train. This made it possible to adjust the pump power of the 980 nm pump to be between 24.58 and 76.75 mW. The operational wavelength of the laser was 1562.9 nm and the repetition rate increased rapidly from 51.9 to 77.1 kHz.
