But what exactly is a laser, how does it work, and how do we use it to do some everyday amazing things? like any other electronic technology, you might just be surprised at how simple it all can be. lasers defined. you can think of a laser as a machine that emits trillions of light particles, called photons, into a precise beam of light.. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.the term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". the first laser was built in 1960 by theodore h. maiman at hughes research laboratories, based on theoretical work by charles hard townes and arthur. How_lasers_work “laser” is an acronym for l ight a mplification by s timulated e mission of r adiation. a laser is created when the electrons in atoms in special glasses, crystals, or gases absorb energy from an electrical current or another laser and become “excited.”.
In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. if you have laser therapy, you may experience less pain. Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. the emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.. Subsequent work introduced the excimer laser for use in angioplasty. xenon chloride (308 nm) excimer lasers can also treat a variety of dermatological conditions including psoriasis, vitiligo, atopic dermatitis, alopecia areata and leukoderma. as light sources, excimer lasers are generally large in size, which is a disadvantage in their medical.
