TS EN ISO 11145

TS EN ISO 11145 is a vocabulary-and-symbols standard for lasers and laser-related equipment. In optics and photonics, this kind of document establishes a common technical language so that manufacturers, users, test laboratories, and technical authors describe the same concepts consistently. In laser technology, precise terminology matters because beam characteristics, operating modes, component names, and graphical symbols can otherwise be interpreted in different ways.

The technical role of a vocabulary standard

The main purpose of this standard is to align how laser-related concepts are named and how they are represented by symbols. In general technical context, lasers are sources of highly directional, often monochromatic light, so terms such as power, wavelength, beam properties, mode structure, and documentation symbols need to be used consistently. A vocabulary standard does not define a device’s performance; instead, it organizes the language used to describe established technical concepts and helps prevent the same idea appearing under different names in different documents.

Why it matters for lasers and related equipment

• Supports consistent terminology in laser-source and accessory documentation.
• Helps align symbols used in optics, electronics, and technical drawings.
• Reduces ambiguity in engineering communication, catalogs, and maintenance documents.
• Promotes the same meaning for the same term across different laser subfields.

This record is withdrawn, so it should not be treated as the current active TSE edition. Even so, the title makes clear that the subject is the vocabulary and symbols associated with lasers and laser-related equipment. Users should understand it as a reference for technical communication and documentation rather than as an experimental standard describing how a device operates.
