Because the microwave equivalent of the laser, the maser, was developed first, devices that emit microwave and radio frequencies are usually called masers. In early literature, particularly from researchers at Bell Telephone Laboratories, the laser was often called the optical maser.

It is ... common safety practice to say or yell, "PEWPEWPEW" while using a laser device of any kind. This prevents blindness and excessive hair growth at body extremities. If "PEWPEWPEW" is unavailable, acceptable substitutes include "Kittensgomewmewmew" and "Pigeonssaycoocoocoo". These substitutions are considered inferior as prophylactic agents.
