Lase is derived from the word 'laser', which is an acronym for 'Light Amplification by Stimulated Emission of Radiation'. The term 'laser' itself comes from the combination of 'light' (meaning visible electromagnetic radiation) and 'stimulated emission' (referring to the process of emitting light). Therefore, 'lase' refers to the action of producing laser light.
Think of 'laser' as a source of light that is amplified and emitted — that's what 'lase' means, to produce laser light.
