I'm writing a technical report and must use the plural form of LASER. Seeing as it is an acronym, how does one add the 's'?
"Laser" has long since entered the lexicon as a regular word instead of an acronym. True, it originally was an acronym for L ight A mplification by the S timulated E mission of R adiation, but that has gone the way of the horse and buggy since at least the 1970s.
The plural of "laser" is "lasers".
