Long Live Lasers!


In 1960, a young Stanford graduate named Theodore Maiman designed and built the world's first working laser. The realization of a concept introduced four years earlier by Arthur Schawlow and Charles Townes of Bell Labs, it used pulses from a photographer's flash lamp to excite atoms in a fingertip-sized ruby crystal, producing a deep red beam. Some might even call it Cardinal. University faculty, students and alumni have made significant contributions to the field ever since, advancing the fundamental science (and earning three Nobel Prizes—booyah!), as well as developing applications in industries as diverse as medicine, electronics, telecommunications, entertainment and the military. Hail, Stanford, hail.
