The word LASER, an acronym for Light Amplification by Stimulated Emission of Radiation, strictly speaking describes a physical process. In connection with its first realization (Maiman, 1960), it has however become common to apply this term for the device that is used for the generation and amplification of electromagnetic radiation.

摘要

The word LASER, an acronym for Light Amplification by Stimulated Emission of Radiation, strictly speaking describes a physical process. In connection with its first realization (Maiman, 1960), it has however become common to apply this term for the device that is used for the generation and amplification of electromagnetic radiation. Depending on its technical design, radiation with very different properties can be generated and used in a wide variety of application fields, such as information technology and metrology, biophysics, medicine, material processing, or fusion research.
