REDONDO BEACH, Calif., April 27 -- TRW Inc. has delivered a solid-state laser designed for industrial applications to the University of Michigan for machining tests. TRW's DP-11A is a 500-W, diode-pumped, solid-state laser suitable for precision drilling, cutting and welding. The laser has been installed at the University's Center for Laser-Aided Intelligent Manufacturing in the School of Engineering. We have two goals for this laser, said Jyoti Mazumder, University of Michigan professor. One goal is to develop a fundamental understanding of how lasers of high brightness work on engineering materials. The second goal is to determine the suitability of the laser for automotive applications, especially for precision drilling of fuel injector orifice disks and welding of aluminum for lightweight auto bodies.
