First light — the birth of the Lab’s laser program

Sixty years ago in 1960, at Hughes Aircraft Company in Malibu, California, Thomas Maiman fired his solid-state ruby laser, emitting humankind’s first coherent visible light. The concept of a laser had been invented by Charles Townes, then a professor at Columbia University, who tested the idea at microwave frequencies in 1953, calling it a maser (now laser, “light” amplification by stimulated emission of radiation). Maiman’s success sparked international competition in laser development for scientific discovery and possible future applications.

Governor Ronald Reagan visits LLNL

In 1967, Ronald Reagan, former movie star and then newly-elected governor of California, visited the Lawrence Radiation Laboratory in Livermore, California to tour the facility and become more informed about major ongoing projects, including work on national defense. While the Laboratory had received a number of distinguished visitors during its first 15 years of operations, it had never hosted a governor of California. As such, on Nov. 22, 1967, Ronald Reagan officially became the first governor of California to visit the Livermore site.
