The first working laser was a ruby laser made by Maiman at Hughes Research Laboratories on 1960.Ruby lasers produce pulses of coherent visible light at a wavelength of 694.3 nm, which is a deep red color.The ruby laser is a three level solid state laser. The active laser medium (laser gain/amplification medium) is a synthetic ruby rod that is energized through optical pumping, typically by a xenon flashtube.
