This article presents the investigative work conducted on the fracture toughness and microstructure of Al6061-9% graphite particulate composites. The requisite specimens for the fracture toughness testing were compact tension ones prepared using stir casting technique. The Al6061-9% graphite particulate metal matrix composite has been heat treated in the underaged condition. It is observed from...
We describe a methodology for designing the optimal gain profiles for gain-based, tunable, broadband, slow-light pulse delay devices based on stimulated Brillouin scattering. Optimal gain profiles are obtained under system constraints such as distortion, total pump power, and maximum gain. The delay performance of three candidate systems: Gaussian noise pump broadened (GNPB), optimal gain-only,...
Optofluidic dye lasers refer to a class of liquid dye lasers, usually on a microfabricated device, in which the adaptive nature of the liquid gain medium allows the dynamical control of the laser properties. Miniaturizing liquid dye lasers onto a microfluidic device not only results in compact, easy-to-maintain and safe dye laser systems, but also provides unprecedented optical performances suc...
در این پایان نامه مباحثی در مورد نیم گروه های معکوس توپولوژیکی اولیه (مطلقا) h-بسته و فشرده (شمارایی) بدست می آوریم و ساختار نیم گروه های معکوس توپولوژی فشرده شمارایی و نیم گروه های معکوس توپولوژی همنهشت-آزاد را توصیف می کنیم و نشان می دهیم که نیم گروه دو دوری نمی تواند در نیم گروه معکوس توپولوژی فشرده شمارایی نشانده شود. we present some discussions about compact (countably) and (absolutely) h...
A major goal in ultrashort wavelength laser research is the development of practical laser sources that can impact applications. Of particular interest is the demonstration of compact “table-top” amplifiers capable of generating soft x-ray pulses of substantial energy. Such development motivates the demonstration of gain media generated by compact devices that can be successfully scaled in leng...
We present the results of a numerical study of active mode locking with hybrid lasers which contain an inhomogeneously broadened laser medium and a homogeneously broadened laser medium. The spectral, pulse, and gain characteristics of actively mode-locked hybrid lasers and the influence of the unsaturated gain, the saturation power, and the homogeneous linewidth on the pulse coherence and bandw...
