LASER means emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation
A laser is a single color beam of light which can used in materials processing for supplying heat energy – whether for laser marking,laser cutting, laser engraving,laser welding or altering the surface properties of a material.
The laser light beam, when focused, provides an intense source of power for marking/engraving,cutting,welding,drilling etc. and is a very popular key method in modern technology for the manufacture of a huge range of products.

LASER can shot with a very narrow spectrum. it can be used to produce ultrashort pulses of light with a broad spectrum but durations as short as a femtosecond, so now have nanosecond,picoseconds, femtoseconds laser in the market,all widely used for more industries.like medical industry etc.
