The Full Form of ‘LASER’ in Technology is ‘Light Amplification by Stimulated Emission of Radiation’.
Full Form of LASER
Laser stands for Light Amplification by Stimulated Emission of Radiation. It is a device that produces and amplifies light through the process of stimulated emission, which occurs when an atom or molecule absorbs energy and then emits it as light.
The concept of stimulated emission was first proposed by Albert Einstein in 1917, and the first working laser was constructed in 1960. Since then, lasers have become an important tool in many fields such as medicine, manufacturing, military applications and scientific research.
In medicine, lasers are used for a variety of applications including vision correction surgery, dental procedures and skin treatments. Laser-assisted cataract surgery is the most common use for lasers in the medical field. Lasers are also used to treat glaucoma, age-related macular degeneration (AMD), diabetic retinopathy and more.
In manufacturing, lasers are used to cut materials such as metal and plastic with high precision and accuracy. This allows manufacturers to create complex shapes that would be impossible to achieve with traditional cutting tools. Lasers can also be used to engrave patterns on materials like wood or glass.
The military uses lasers in a number of ways including target acquisition systems, rangefinders, missile guidance systems and nonlethal weapons such as dazzlers or stroboscopes that temporarily blind people without causing permanent damage. Lasers can also be used to detect submarines underwater or identify targets at long distances using the reflected laser beam.
Lasers have been integral in scientific research since their invention; they’re used for microscopy, spectroscopy studies and measuring distances between celestial bodies in space. For example, astronomers use powerful laser beams from Earth to measure distances between stars in our galaxy accurately up to several hundred million light years away from Earth!
Laser technology has come a long way since its inception over 60 years ago; it is now an indispensable tool across a wide array of industries from manufacturing to medicine and astronomy! The full form of LASER – Light Amplification by Stimulated Emission of Radiation – truly reflects its incredible capabilities!
