How it's used
Although 鐳射 is widely understood and used in Hong Kong, it is a direct phonetic loan from English. Many younger speakers or those in technical fields now prefer the term 雷射, which is more common in Taiwan and mainland China, or simply use the English word laser directly in conversation. It is common to see it used in product names or descriptions for office equipment.

Common mistake
Do not confuse this with the Cantonese word 激光, which is the standard term used in mainland China and increasingly in Hong Kong for laser. While 鐳射 is perfectly acceptable, using 激光 might be preferred in formal or scientific contexts.
