Abstract

Over the past few years copper vapor lasers have become an important tool in high speed photography as a high-tech strobe lighting source. The short flash duration ( 025 microseconds) high brightness (of the order of 20 million Lumens) and high flash rates (32 per second from a single laser 96 per second from three lasers) of copper vapor lasers have enabled high resolution analysis of processes that previously could not be explored using conventional incandescent continuous or strobe lighting sources. A summary of applications that have benefited from the use of copper laser lighting will be presented. These applications include: analysis of shock waves in turbine engine blades analysis of spinning fibers in the textile industry analysis of the bursting of high pressure storage vessels analysis of turbulent flow in internal combustion engines and capture of ballistic data of objects travelling in excess of 1500ms1(3 mph). Discussion of why copper laser lighting was crucial in each of these applications will be presented.
