laser
Let an agent explain lasers and how they work, relay types, applications and safety classes from physics and standards sources, describe medical and industrial uses, and note weapon applications without operational detail.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain lasers and how they work, relay types, applications and safety classes from physics and standards sources, describe medical and industrial uses, and note weapon applications without operational detail.
A device that emits a coherent, narrow and often intense beam of light through stimulated emission of radiation in a gain medium within an optical cavity, in forms such as gas, solid-state, fibre and semiconductor laser diodes, used in communications, medicine including dental lasers, manufacturing, surveying with airborne laser scanners, entertainment, scientific research and, at a public reference level, in high-energy laser weapons such as the Tactical High Energy Laser; lasers are classified by hazard and regulated for eye safety.
What it is for: Producing coherent light for many applications.
It can be explain the principle and types; relay applications; relay safety classes; note weapon applications non-operationally.
