Experimental Ruby Laser

<< >>
Description
This is an experimental ruby laser made in 1963 at Ohio State University. Edward Damon, a researcher at the University’s Antenna Laboratory, made this and several other lasers during his investigation of Theodore Maiman’s successful ruby laser experiments of three years earlier.
An important part of science consists of replicating the experiments conducted by other researchers and confirming their results. Like Maiman's 1960 laser, Damon's 1963 laser used a photographer's helical flashlamp to energize the ruby crystal. It demonstrated the use of mirrors external to the ruby rod instead of mirrors deposited in the crystal itself. The mirrors are on adjustable mounts that allowed Damon to make a variety of experiments with this unit.
