Abstract: Graphene is a 2-D carbon nano material with very excellent optical properties. Passive Q switches, by using its saturated absorption characteristics, have such advantages as stability, wide responding wavelength from the visible to mid-infrared wavelength region, low nonsaturable loss, ultrafast recovery time (about 100fs), easy fabrication and low cost and have been used in passive Q-switched pulse laser widely. The research progress of graphene passively Q-switched Nd3+-doped lasers was reviewed and the future development of this filed was discussed. The excellent graphene saturable absorber is the key to its development.
