Comparative study of Q-Switched erbium doped fibre laser with SWCNT-PVA saturable absorber of different ratios.

This paper intends to compare the performance parameters of passive Q-switched erbium-doped fibre laser (EDFL) ring cavity configuration by employing SWCNT-PVA as a saturable absorber (SA). The single-wall carbon nanotube-polyvinyl alcohol (SWCNT-PVA) SA thin film fabricated by drop-casting techniqu...
