Explanation:
Noble gases and halogens can combine to form lasers called Excimer, for this to happen the noble gas must be ionized with a high voltage discharge, thus forming a molecule of the type
noble gas (X) + halogen (H) → XH
This molecule is highly unstable and decomposes within a few nanoseconds, emitting light in the UV range.
