Abstract: PURPOSE: An ultra fast carbon nano tube saturable absorber for a solid-state laser mode-locking is provided to operate a solid-state laser with the repetition rate of 89 megahertz when applying to a Yb: KLu(WO4)2 solid laser. CONSTITUTION: An ultra fast carbon nano tube saturable absorber for a solid-state laser mode-locking is manufactured by a step of forming a carbon nano tube solution by mixing a single-walled carbon nano tube(SWCNT) produced from an electric discharge to diclobenzene, a step of missing the carbon nano tube solution with polymethyl methacrylate(PMMA) to produce a SWCNT/PMMA composite, and a step of forming a thin film with the SWCNT/PMMA composite by a spin coating method on a substrate.

Abstract: PURPOSE: A saturable absorber including monolayer graphene and a manufacturing method thereof are provided to emit the ultrashort pulse of a femto second in a broadband wavelength domain using a saturable absorber in solid laser oscillation. CONSTITUTION: A single layer graphene is formed on the top part of a substrate. The area of the single layer graphene is 1-1.44cm^2. The substrate is made of optical glass. The substrate is formed into a reflection mirror. A mixed gas including the alkane of C1-C10, hydrogen, and argon is applied on the substrate which is coated by a metallic foil at a temperature of 500-2000°C. A stamp material is coated on the graphene. A graphene and stamp composite and the substrate are separated by etching the metallic foil. The graphene and stamp composite is obtained by separating the grapheme and stamp composite and the substrate. The graphene and stamp composite is mapped on other substrate. The stamp is removed.
