1960s: acronym from light amplification by stimulated emission of radiation, on the pattern of maser.
radar from [M20]:
This system for detecting objects by sending out radio waves which are reflected back was developed in the 1930s. The name comes from the opening letters of radio detection and ranging, and was coined in 1941. Police started using radar traps to detect speeding motorists in the early 1960s. In the Second World War the myth that pilots ate lots of carrots to help them see in the dark was spread to explain how they could detect enemy planes, as radar was still a secret. Other words have been coined on the pattern of radar, such as lidar (mid 20th century), which works like radar, but uses light from lasers (mid 20th century)—laser itself being an acronym from ‘light amplification by the stimulated emission of radiation’.
