Compared ultraviolet lasers and ultraviolet light

The Substance composed of atomic generates enormous amounts of thermal energy after the release of out . this is light .the atomic is rather unstable near After gaining the energy(Spire the state of atomic) and ultimately transform it into light forms. due to different light resource will be produce different sorts of light. for example : ultraviolet lasers and ultraviolet light.Deep ultraviolet lasers and uv led strip have various applications in industries and scientific researches. of course also say some difference in common.
First find out what same point:

They are all electromagnetic wave(ultraviolet lasers and ultraviolet led strip and other electromagnetic waves transfer momentum and energy through space). Theyonly have a fixed wavelength.

What’s s main different between ultraviolet lasers and ultraviolet light?
The ultraviolet lasers is single frequency of high Energy Beam. energy density is higher than ultraviolet light.
