Mechanical Engineering Department. Motilal Nehru National Institute of Technology Allahabad. Other spectroscopic techniques based on lasers can be used to make extremely sensitive detectors of various molecules, able to measure molecular concentrations in the parts-per-trillion ( ppt ) level.
Due to the high power densities achievable by lasers , beam-induced atomic emission is possible: this . Production of green laser Green Gap Problem Solution to Problem 5) Applications in detail.
Originally LASER was an acronym for Light Amplification by the Stimulated Emission of Radiation.
Electromagnetic Spectrum The emission of light is fundamentally related to the behavior of electrons.

Lasers are important tool in our everyday lives and is applied to more and more everyday things as technology becomes more and more advanced. LASERS HELPED IN UNDERSTANDING AND OFFERING CLARIFICATIONS FOR MANY BASIC PROBLEMS OF SCIENCE AND TECHNOLOGY. LASER BEAM WELDING(LBW) LASER - Light Amplification by Stimulated Emission of Radiation Focusing of narrow monochromatic light into extremely concentrated beams (mm even) Used to weld difficult to weld materials, hard to access areas, extremely small components, In medical field to weld detached . Effects of laserThe advances in laser technology have resulted in laser beams becoming commonplace.
We use lasers every day, often without realizing were doing so. Future advances in laser technology will undoubtedly produce improvements in the areas of entertainment, medicine, dentistry, computing .
