G'day.
Sorry to interrupt with a pretty simple question but, while Wikipedia and many, many Chinese suppliers discuss fib(er|re) las(er|re)s using the word Faserlaser, many high-end German suppliers themselves seem to prefer the word Farblaser for similar products. Wiktionary has no entries on any of them. Are they complete synonyms that can be used interchangeably? or is there a nuance I'm not picking up on?
