摘　　要：石墨烯是一种具有独特光学特性的2维碳纳米材料,利用其饱和吸收特性制成的被动调Q开关具有稳定性好、响应波长宽(可见光到中红外)、恢复时间短(约100fs)、非饱和吸收损耗少、制作方法简单、价格便宜等优点,广泛地应用于被动调Q脉冲激光领域。重点对石墨烯被动调Q掺Nd3+激光器研究进展进行了总结,分析了发展趋势,并指出性能优良的石墨烯饱和吸收体是其发展的关键。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.
