Laser Applications

Lasers have become an indispensable part of our lives with utilities in consumer electronics, communications, sensors, and medicine. Every single compact disc player contains semiconductor laser, and airplanes rely on laser gyroscopes for navigation.  Lasers are used up for photocoagulation of the retina to stop retinal discharging and for the tacking of retinal tears. Apart from this laser suits application in the garment industry, surveying and ranging, barcode scanners. Around 50 years back, CU graduate Theodore Maiman (Engineering Physics '49) showcased the world's first working laser, that is the ruby laser at Hughes Research Laboratories in Malibu, California.
 

Medical Lasers:  Medical lasers are exploited as a scalpel. Since the laser can be controlled and can have such a small contact area it is perfect for depth control and fine cutting. Medical lasers can likewise be utilized to reattach retinas and might be used in combination with fiber optics to place the laser beam where it needs to be.  Medical lasers are applied to stitch up incisions after surgery, by fusing skin together.
 

Entertainment: Laser shows are quite famous and the special effects are bewildering.  These make use of lasers that are in the visible range alongside vibrating mirrors to paint images in the air.

Metal working: Lasers permits improved cuts on metals and the welding of dissimilar metals without the use of a flux.  Furthermore lasers can be fixed on robotic arms .This is safer then oxygen and acetylene, or arc welding.
