Hello there!
Greetings!
A laser is a device that emits a beam of coherent light through an optical amplification process. There are many types of lasers including gas lasers, fiber lasers, solid state lasers, dye lasers, diode lasers and excimer lasers. All of these laser types share a basic set of components.
There are many applications for laser technology including the following:
- Laser Range Finding
- Information Processing (DVDs and Blu-Ray)
- Bar Code Readers
- Laser Surgery
- Holographic Imaging
- Laser Spectroscopy
- Laser Material Processing
- Cutting
- Engraving
- Drilling
- Marking
- Surface Modification
Lasers are used in optical disk drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic and free-space optical communication, laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range
Thankyou
