Optics fluence

WebOct 12, 2011 · Max-of-N fluence is the maximum peak fluence at a given location over N number of shots and is important for calculating fluence dependence for intrinsic laser-induced optic damage. Previously, we observed the Max-of-N effect on the National Ignition Facility and developed an ad-hoc model to calculate its effect. WebThe objective of this study is to investigate third-order optical nonlinearities of monolayer and randomly stacked bi- and four-layer graphene samples, depending on wavelength and …
