Pulse Delivered by Hollow Optical Fiber Creates Spark

Research shows that significant improvements in combustion efficiency can result when the igniting spark in an internal combustion engine is in the center of the cylinder rather than along the walls or near the electrodes, where the ignition kernel can be thermally quenched. One way to get the spark away from the cylinder walls is to use a laser-created spark. However, to be practical, open-path beam delivery should be avoided. A potential solution is to use an optical fiber to pipe in the high-intensity laser pulse. Although this technique currently is impractical economically for...Read full article
