PURPOSE: A manufacturing method for a mode rocker and a pulse laser apparatus using the same are provided to manufacture a pulse laser by manufacturing a mode rocker using an optical non-linearity of a graphene/ polymer composite. CONSTITUTION: Graphite powder is dissolved in sulfuric acid with sodium nitrate(S301). A cleaning process using deionized water is carried out(S302). A graphene oxide is dried in room temperature(S303). The dried graphene oxide is dispersed in the sulfuric acid which is cooled(S304). The sulfuric acid including KMnO4(potassium permanganate), phosphoric acid, and the graphene oxide is filtered(S305) The mixture of the sodium nitrate and the graphene oxide is successively washed in DI, hydrogen peroxide liquid, and hydrochloride(S306). The washed mixture is processed with ultrasonic waves in the DI(S307). An organic solvent and hydrazine or ammonia and hydrazine are added to a solution including the graphene oxide(S308). A graphene/polymer composite is obtained(S309).

PURPOSE: A method for manufacturing a SWNT(single wall nanotube-ceramic composite) and an optical nonlinear element manufactured by the same are provided to obtain the uniformly dispersed SWNT by dispersing the SWNT to silica. CONSTITUTION: A mixture of a SWNT and silica powder is prepared using ball milling. The mixture of the SWNT and the silica powder are repetitively injected to an end surface of an optical fiber ferrule as powder using a nozzle. The mixture is uniformly injected to the end surface of the ferrule by reciprocating the optical fiber ferrule. The mixture is coated on the end surface of the ferrule as a predetermined thickness of a film form by controlling reciprocating speed and the number of repetitions.
