TS EN ISO 11145

TS EN ISO 11145 is a vocabulary and symbols standard for lasers and laser-related equipment. Standards of this kind create a common technical language so that the same laser concepts are understood consistently across manufacturers, laboratories, integrators, and users. This TSE record belongs to a withdrawn edition, but the title clearly identifies its subject: the naming and symbolisation of terms used in laser and photonics documentation.

Why laser terminology matters

AS GENERAL TECHNICAL CONTEXT, laser work depends on precise terminology. Terms are used to distinguish continuous and pulsed operation, beam characteristics, wavelength, output power, modes, and related safety or documentation concepts. Clear definitions reduce ambiguity in datasheets, drawings, manuals, procurement documents, and test reports. Symbols and abbreviated forms help present this information in a compact, standardised way that can be shared internationally.

What this subject covers conceptually

• Core naming conventions for lasers and laser systems
• Related equipment and supporting components used with laser setups
• Symbols and abbreviations used in technical documentation
• Common terminology needs in optics and photonics engineering

From the title alone, this standard should be understood as a language-and-symbols reference rather than a performance or test-method document. Its purpose is not to define how a laser must be designed or what output it must achieve, but to support consistent communication about laser-related equipment. That consistency is especially valuable in laboratories, manufacturing, integration work, and maintenance environments where technical meaning must remain exact.
