The efficient passive mode-locking of a Ti: sapphire laser with a monolayer graphene saturable absorber is demonstrated for the first time. High-quality and large-area (1 in.) monolayer graphene, synthesized by chemical vapor deposition, exhibits ultrafast recovery times and excellent nonlinear absorption behavior for bulk solid-state laser mode-locking near 800 nm. The continuous-wave mode-locked Ti: sapphire laser generates 63-fs pulses with output powers up to 480 mW under stable operation at 99.4 MHz. (c) 2012 The Japan Society of Applied Physic
