The experimental investigation to explore the generated laser output by using newly developed copper nanoparticle (Cu-NP) as a saturable absorber (SA) at 1550 nm operating region is presented. Accordingly, the light-material interaction between copper nanoparticles and PolyVinyl-Alcohol (PVA) film interpreted onto the modulation depth of Cu-NP was recorded at about 36 (0.14)% wherein the laser ring cavity consists of all-fibre components that are compatible with the proposed operating window. A similar to 1.88 MHz passively soliton mode-locked at 1564.3 nm with pulse-width of 2.85 (0.16) ps and 7.95 (1.7) nJ of maximum pulse energy was successfully generated. Moreover, the high signal to noise ratio of 71 dB while maintaining long term stability as well as low threshold power suggests that the properties owned by pure copper nanoparticles as a great alternative towards conventional saturable absorber.
