Effects of flake size on mode-locking behavior for flake-graphene saturable absorber mirrors
نویسندگان
چکیده
After advent of graphene as a saturable absorber many experiments have been conducted to produce short pulse duration pulses. Here, we have measured the properties of flake-graphene saturable absorber mirrors of various flake sizes dependent on fabrication technique. These mirrors enabled us to obtain a large mode-locking bandwidth of 16nm in an erbium-doped fiber laser. Mirrors with large flake size and multi-layered thickness induce strong pulse shaping and reflect modelocked train of pulses with very large bandwidths.

Ultrafast laser sources have garnered considerable attention for their many potential applications, ranging from meteorology to telecommunications, medicine, and materials processing. Most of these lasers employ a mode-locking technique in which a nonlinear optical element, called a saturable absorber,turns the laser's continuous wave output into a train of ultrashort optical pulses. Currently,...

An ultra-broadband graphene-gold film saturable absorber mirror (GG-SAM) with a spectral coverage exceeding 1300 nm is experimentally demonstrated for mode-locking of bulk solid-state lasers. Owing to the p-type doping effect caused by graphene-gold film interaction, the graphene on gold-film substrate shows a remarkably lower light absorption relative to pristine graphene, which is very helpfu...
