Definition

Meaning

The action of a substance or device emitting coherent light through stimulated emission, as in a laser.

The process of generating laser light; functioning as a laser. Sometimes used informally to describe intense, focused activity.

Linguistics

Semantic Notes

"Lasing" is the gerund or present participle of the verb "to lase." It is a back-formation from the noun "laser." Its use is almost exclusively confined to physics, engineering, and related technical fields.

Examples

By Part of Speech

verb

British English

  • The new diode began to lase at room temperature.
  • The crystal won't lase without the correct pump energy.

American English

  • The prototype finally lased after we adjusted the mirrors.
  • This material can lase across multiple wavelengths.

Learning

Memory Aids

Mnemonic

Think: "LAser + actING = LASING." It's what a laser is DOING.

Conceptual Metaphor

A precise, focused, and amplified stream of energy (used informally).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with "лазинг" (climbing) or "лазание." The correct technical translation is "генерация лазерного излучения" or simply "лазерная генерация." The verb "to lase" is often translated as "генерировать лазерное излучение."

Common Mistakes

  • Using 'lazing' (relaxing) instead of 'lasing.'
  • Using it as a general synonym for 'shining' or 'glowing.'
  • Misspelling as 'lazer-ing.'

FAQ

Frequently Asked Questions

Yes, it is a standard technical term in physics and engineering, derived from the acronym LASER.

No, that is 'lazing.' 'Lasing' is a technical term related to lasers.

It is most commonly used as a verb (present participle/gerund) or a participial adjective.

Extremely rarely, and only in informal, metaphorical extensions (e.g., 'his mind was lasing with ideas') which are not standard.
