Lasers

Old Dominion University is always looking for ways in which professors of different disciplines can work together. Professor Mournir Laroussi, (left) electrical and computer engineering and Assistant Professor Venkat Maruthamuthu, mechanical and aerospace engineering, have found a way to generate a diffused plasma inside a chamber without applying any electrical power to the chamber. Since there are no electrodes inside the chamber, there is no contamination and no need for electrode replacement. Photo Chuck Thomas/ODU
