The single-walled carbon nanotube (SWCNT) polymer with thickness of 30 μm is demonstrated to passively mode-lock the erbium-doped fiber laser (EDFL) with the optimized pulsewidth of 792 fs under a pumping power of 52.5 mW.
A pumping-power-dependent high-order harmonic mode-locking erbium-doped fiber laser (HML-EDFL) with a single-wall carbon nanotube (SWCNT)-doped polyvinyl alcohol (PVA)-based saturable absorber is investigated. The HML-EDFL systems using either all-physical-contact (PC) or all-angled-physical-contact (APC) connectors examined in this study show stably mode-locked pulse trains; however, the all-PC connector-based...
The single-wall carbon-nanotube doped PVA saturable absorber induced 6th-order harmonic passively mode-locking fiber ring laser with pulsewidth and spectral linewidth of 2.16 ps and 0.476 nm with 60 dB of SNR is demonstrated.
The iron silicide thin-films prepared by thermal diffusion of Iron nanoparticles into Si Substrate at 900°C in pure N2 environment is demonstrated to show strong room-temperature photoluminescence (PL) at 1.55 μm. The increase of iron nanoparticle concentration from 7.4 wt% to 19 wt% further effectively enhances the room-temperature PL intensity.
