🔄 Synonyms & Antonyms?
Synonyms (Words with similar meaning):
- Lichtstrahl: More general ('light beam'), but often used in the context of lasers when referring to the beam.
- Strahl: Even more general ('beam', 'ray'), needs context.
- (No direct technical synonyms for the device itself, as 'Laser' is the specific term).
Antonyms (Opposites):
- There isn't a direct antonym for 'Laser'. One might consider non-specific, incoherent light (like from an incandescent bulb - Glühbirnenlicht) as an opposite concept, but it's not a standard antonym.
Potential Confusion? ⚠️

- Taser: An electroshock weapon; sounds similar but completely unrelated to light.
