| Abstract: |
This research presents the experimental demonstration of Chromium Gallium Carbide (Cr2GaC) as a saturable absorber (SA) for the generation of Q-switched pulses within an erbium-doped fibre laser (EDFL) cavity. The structure was created by combining conductive materials with a polymer matrix. The SA was later utilized in two different configurations for pulse generation. A success stable Q-switched operation was as attained by adjusting the loss and gain within the cavity, utilizing pump powers between 25.98 and 53.67 mW. Throughout this interval, the repetition rate rose from 45.37 to 70.42 kHz, concurrently with a reduction in pulse width from 5.72 to 3.2 µs. The Q-switched EDFL functioned at a central wavelength of 1558.7 nm, providing a peak pulse energy of 31.24 nJ and achieving a slope efficiency of 4.9%. The results highlight the potential of Cr2GaC-based saturable absorbers for effective Q-switching in fibre laser systems. [ABSTRACT FROM AUTHOR] |
