History of Lasers
Posted in Resources at 9:12 pm
Every good nerd should know something about the history of lasers. I searched for a good (and brief) history and the best I found was on Wikipedia:
In 1957, Charles Hard Townes and Arthur Leonard Schawlow, then at Bell Labs, began a serious study of the infrared laser. As ideas were developed, infrared frequencies were abandoned with focus on visible light instead. The concept was originally known as an “optical maser”. Bell Labs filed a patent application for their proposed optical maser a year later. Schawlow and Townes sent a manuscript of their theoretical calculations to Physical Review, which published their paper that year (Volume 112, Issue 6).
