TS EN ISO 11145

TS EN ISO 11145 is a vocabulary standard for lasers and laser-related equipment, bringing together the terms, definitions, and symbols used in optics and photonics. Its purpose is to support a common technical language so that the same concepts are understood consistently across manufacturers, laboratories, and technical documents. The focus of this standard is not how laser equipment is built, but how laser terminology is named and represented.

Why laser terminology needs a common language

In laser technology, concepts such as beam quality, output power, wavelength, pulsed operation, continuous-wave operation, and beam characteristics are central to design, measurement, documentation, and safety-related communication. Because these terms are used across many applications, consistent definitions matter. In general technical context, a vocabulary standard like ISO 11145 helps reduce ambiguity and aligns terminology across disciplines without necessarily introducing new performance requirements.

Symbols and technical documentation

The inclusion of symbols in the title indicates that the standard also addresses the graphical or symbolic notation used in laser and optoelectronic documentation. This is important in drawings, datasheets, catalogues, and engineering records, where precise notation helps prevent confusion between measured quantities and their meanings. As a withdrawn TSE edition, this listing is no longer in force, but it remains relevant as part of the established terminology framework for laser technology.
