Amplification by stimulated emission of radiation

The Spring Meeting of the New York State Section of the American Physical Society was held at LeMoyne College in Syracuse on April 14 and 15, 1961. More than 250 persons attended, mainly from the New York state area, although a few came from as far as California. This was the fourth in a series of highly successful semiannual meetings, each devoted to a selected current topic in physics. In contrast to Physical Society meetings on a national scale and topical conferences where research workers exchange ideas with others in the same field, each of these meetings is designed to bring to physicists the latest developments in an important and rapidly growing area of physics not generally their speciality. Meetings are held at various locations in the state, frequently upon invitation by a company or university. Previous meetings of the current series have been held at Rochester on fuel cells, at Hamilton on radio astronomy, and at Binghamton on computers.
