Abstract: An apparatus which can confine almost entire available energy in the vicinity of ignition point during a laser-induced ignition process is proposed. Multiple reflection by a cavity surface when a small diameter laser beam is directed into the cavity is utilized in laser ignition. Shadowgraphs of the early stages of the combustion process for quiescent methane/air mixtures show that a hot gas jet emerges from the cavity. During subsequent flame propagation, both similarities with and difference from conventional spark ignition processes are observed, depending on the cavity size and the concentration of mixtures. With laser cavity ignition, the chamber pressure increases relatively rapidly and higher maximum pressure can be achieved. As a result, the combustion duration for laser cavity ignition is decreased relative to laser-induced spark ignition.

Abstract: A method of fabricating a thin film transistor includes crystallizing an amorphous silicon layer having a sloping surface and a flat surface by an SLS technique using a laser beam having predetermined energy density so as to melt the sloping surface as well as the flat surface of the amorphous silicon layer to form a crystallized silicon layer and forming the active layer by selectively etching the crystallized silicon layer. The laser beam is applied non-vertically to the sloping surface while the laser beam is applied vertically to the flat surface. Although the sloping surface and the flat surface of the amorphous silicon layer are irradiated with a laser beam having the same laser energy density, the absorbed energy density of the sloping surface may be lower than that of the flat surface. The laser beam generates a first energy density to substantially melt the sloping surface and a second energy density to substantially melt the flat surface of the amorphous silicon.
