Lasers are used in almost every field varying from Biology, Astronomy, Industry, Research etc.
For example:
-
Medical use: Dermatology, Eye surgery (Lasik), Gastro-intestinal tracts etc.
-
Biological research: Confocal Microscopes, Fluorescence Microscopes, Atomic Force Microscope, Laser Raman Microscopes (All these are used for cell, DNA and protein studies) etc.
-
Physics research: Thin Layer deposition, Scanning Tunneling Microscopes (STM) etc.
-
Astronomy: Used in big optical telescope facilities to get track of atmospheric activity.
-
Industry: Metal cutting using lasers, welding, lithography, holography.
-
Daily life: Laser Printers, Laser Mice (computer), Burglar Alarm systems, Laser pointers, CD/DVD/Bluray players, Playstation, xbox, Wii, Laser tag (I guess you know what it is), Lighting in clubs and concerts.
Oh ! I forgot, The military weapons, whether its guns, missiles or drones, almost all of them use lasers.
The full list is never ending.
