We demonstrate the generation of noise-like pulse (NLP) in L-band erbium-doped fiber laser incorporating nano-tungsten trioxide and polydimethylsiloxane (WO3/PDMS) decorated onto a tapered fiber structure. A Raman pump unit with 3.5 W pump power was employed for a core-pumping scheme of 7 m long hig...
