Lasers are used for photocoagulation of the retina to halt retinal hemorrhaging and for the tacking of retinal tears. Higher power lasers are used after cataract.
Many scientific, military, medical and commercial laser applications have been developed Lasers have been used aboard spacecraft such as in the Cassini- Huygens mission. In astronomy, lasers have been used to create artificial laser.
Lasers are widely used in manufacturing, e.g. for cutting, drilling, welding, cladding, soldering (brazing), hardening, ablating, surface treatment, marking.
Medical lasers can be used as a scalpel. Since the laser can be controlled and can have such a small contact area it is ideal for fine cutting and depth control.
Lasers are an integral part of the technology we depend on every day and their widespread use continue to evolve. But what are lasers really.
How do the flash tube and the crystal make laser light? How is of such technology as far as I encountered, observed, used, or read about.
