Large energy mode locking of an erbium-doped fiber laser with atomic layer graphene discuss this article 1 Comment
Source: Optics Express Category: Physics
Latest Comment by hanzhang - November 18, 2009: It is further confirmed that such unique absorption could become saturated when the input optical intensity is above a threshold value. This nonlinear optical behavior is termed saturable absorption and the threshold value is called the saturation fluency. Graphene can be saturated readily under strong excitation over the visible to near-infrared region, due to the universal optical absorption and zero band gap. This has relevance for the mode locking of fiber lasers, where wideband tuneability may be obtained using graphene as the saturable absorber. Due to this special property, graphene has wide application in ultrafast photonics.
