laser technology
Focused beam science
Laser technology encompasses devices and techniques using lasers—focused beams of coherent light produced by stimulating atoms to emit photons in sync.
Applications span medicine (surgery, vision correction), manufacturing (cutting, welding), communications (fiber optics), measurement (surveying, ranging), and entertainment (light shows, disc players).
Laser technology has revolutionized eye surgery.
