Abstract

The idea of using a laser for materials processing is more than 20 years old. Although the concept of a non-contact method for processing with a beam of light has been pursued with great interest and enthusiasm, the practical use of laser beam processing was slow to develop. The lasers available in the 1960's were fragile and of relatively low power. In the 1970's lasers in the multi-kilowatt range were developed but the problem of laser acceptance by the customer had to be overcome. Today, reliable Nd-Yag and CO2-lasers are available and laser processing is a fast growing market. An additional boost is expected with the development of the next generation of lasers and with increased knowledge of the physical phenomena that underlie laser material processing. This paper will review latest developments in laser technology and laser-workpiece interaction with special emphasis on the impact of high speed photography on the research work in these areas.
