LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. To lase is to absorb energy in one form and emit a new more useful form of energy.

Lasers were first conceptualized by Albert Einstein (1917). The first prototype photothermal laser was built by Theodore Maiman (1960), and they have since become essential tools in ophthalmic practice. Recent technological advances and new concepts have renewed interest in the topic.

Lasers can be generated in a spectrum of wavelengths (short UV to long IR) with a multitude of applications including electronics, information technology, science, medicine, entertainment, military, industry, and law enforcement. Modern fibre- optic communication technology such as the Internet uses lasers.
