Q-Switched Erbium-doped Fiber Laser Based on Silicon Nanosheets as Saturable Absorber

Aluminium zinc oxide as a saturable absorber for passively Q-switched and mode-locked erbium-doped fiber laser

“…Our results are comparable to recent year studies which use PVA as a host polymer [29,37]. Table 1 sums up the comparison of Q-switched operation including zinc oxide SA and our previous work based on silicon oxycarbide as a SA [30,37,38]. The comparison to previous studies show that a higher average output power of 4.1 mW is achieved, contributing to the optimized EDFL configuration.…”

“…The experimental work on Q-switched performance of AZO-PVA thin film as a SA is comparable to some recent works reported on Q-switched operation in EDFL. Recently, Liu et al [37] have reported silicon nanosheets (Si-PVA) based SA for Q-switched where the maximum average output power was 0.89 mW and shortest obtained pulse width was 2.32 µs. Our results are comparable to recent year studies which use PVA as a host polymer [29,37].…”

Bulk α-alumina embedded tapered fiber as Q-switcher in an erbium-doped fiber laser

“…The maximum output power of 6.5 mW was recorded at 308.60 mW pump power. As the pump power exceeded this value, the Q-switched pulse became unstable and eventually collapsed, which was also observed in the previous studies [13,21]. The pulse operation could be restored again by lowering the pump power below 308.60 mW.…”

Q-switched pulse operation in erbium-doped fiber laser subject to zirconia (ZrO2) nanoparticles-based saturable absorber

“…This leads the laser towards switching of laser output from a CW state to a pulsed state. Recently, several efforts have been dedicated towards the fabrication of SAs through the utilization of chemical vapor deposition [ 11 ], liquid-phase-epitaxy [ 12 ], nano-powder [ [13] , [14] , [15] ], solution methods [ 16 ], pulsed laser deposition-based thin films [ [17] , [18] , [19] ] and then incorporating the nanostructures or thin-film material within the laser cavity which has significantly enhanced the performance and efficacy of pulsed fiber laser sources.…”
