"...there's a great affinity between writing poetry and SF."
The lasgun is another in a series of laser-based weapons; the descendant of the "blasters" of the science fiction of the 1920's.
Its use as a weapon is limited by subatomic fusion that occurs when the beam of a lasgun (offensive weapon) intersects that of a shield using the Holtzman field (defensive weapon). See the blaster (1925) from When the Green Star Waned by Nictzin Dyalhis, the neutron blaster (1951), from The Complete Paratime, by H. Beam Piper and the heat ray from The War of the Worlds (1898), by H.G. Wells.
Compare to nuclear shears from Foundation (1951) by Isaac Asimov, the
toaster from Accidental Flight (1952) by WF Wallace, the
Slaver disintegrator from Ringworld (1970) by Larry Niven and the
atomic torch from One Against the Legion (1939) by Jack Williamson.
