TS EN ISO 11145

TS EN ISO 11145 is a terminology standard for laser technology that defines basic terms, symbols, and units of measurement used to express beam parameters and laser-related product properties in a clear and consistent way. It was developed to reduce ambiguity in the language used for lasers and laser equipment and to support more understandable, comparable measurement and test communication.

A common language for laser technology

Laser technology brings together concepts such as wavelength, output power, beam quality, focusability, and directionality. The focus of this standard is the core vocabulary that ties those ideas together: the laser itself, laser-related equipment, beam parameters, and the symbols used to represent them. In general technical practice, a shared vocabulary helps engineers, test laboratories, and manufacturers describe the same phenomenon in the same way, which improves consistency across documentation and measurement records.

Terms that support measurement and test communication

According to its scope, the standard provides the terms needed to arrive at clear definitions and reproducible tests of beam parameters and laser-oriented product properties. Its role is to define how these characteristics are named and expressed, not to guarantee any specific device performance on its own. In the laser field, precise terminology matters because power, energy, continuous-wave or pulsed operation, beam diameter, and related concepts must be handled without confusion.

This listing represents a withdrawn edition of TS EN ISO 11145. It remains useful as a conceptual reference for laser terminology and symbols, while the current status of the standard should be considered separately.
