The free-electron type of this device uses synchrotron radiation from an undulator, and the predecessor to this device operates with microwaves and was initially based on ammonia.

One of these devices, the YAL-1, is situated in a Boeing 747, and these devices require (*) population inversion in order to operate. Common varieties of these devices are based on carbon dioxide and a helium-neon mixture, but most sold are of the diode type. Based on the principle of stimulated emission, for 10 points, name these devices which emit coherent light, used in printers, CD players, eye surgery, and handheld pointers.
