Abstract Tungsten disulfide (WS2) & Graphene oxide (GO) based saturable absorber (SA) was demonstrated and studies for passively Q-switched mode-locked Nd:GdTaO4 laser. The fabrication process of mixed SA was described. Passively Q-switched mode-locked operation with sub-600ps pulses was obtained by using this SA. Taking into account the simpler manufacturing progress, larger single pulse energy and better modulation depth, the mixed WS2-GO saturable absorber seems to be good way as suitable saturable absorber for solid state lasers.
