Accurate and Efficient Modeling of the Transverse Mode Instability in High Energy Laser Amplifiers
Curtis R. Menyuk, Joshua T. Young, Jonathan Hu +3
We study the transverse mode instability (TMI) in the limit where a single higher-order mode (HOM) is present. We demonstrate that when the beat length between the fundamental mode…

Photoacoustic Identification of Laser-induced Microbubbles as Light Scattering Centers for Optical Limiting in Liquid Suspension of Graphene Nanosheets
Qiuhui Zhang, Yi Qiu, Feng Lin +8
Liquid suspensions of carbon nanotubes, graphene and transition metal dichalcogenides have exhibited excellent performance in optical limiting. However, the underlying mechanism ha…

Graphene Induced Large Shift of Surface Plasmon Resonances of Gold Films: Effective Medium Theory for Atomically Thin Materials
Md Kamrul Alam, Chao Niu, Yanan Wang +15
Despite successful modeling of graphene as a 0.34-nm thick optical film synthesized by exfoliation or chemical vapor deposition (CVD), graphene induced shift of surface plasmon res…
