Abstract
The graphene was synthesized by two routes the 1st one application of conventional sonication in case of Tri-chloro-acetic 75%H2SO3 for 60hrs while 2nd is combined sonication (60 hrs) plus laser irradiations for 30hrs . The yields of two routes are collected and compared structurally to check and investigate the effect of laser on structure quality and amount of yield obtained . Results indicated that combined route gave yield higher than conventional route by ratio ~ 39% .AFM-investigations were performed to characterize nano-structural features of produced graphene . .Furthermore raman spectra were measured to confirm graphene formation .

Keywords
