Solid-state lasers
Have lasing material distributed in a solid matrix
![Page 14: Exploring laser systems - Zewail city](https://reader034.vdocuments.us/reader034/viewer/2022051404/58e821151a28ab1b298b5759/html5/thumbnails/14.jpg)
Gas lasers
![Page 15: Exploring laser systems - Zewail city](https://reader034.vdocuments.us/reader034/viewer/2022051404/58e821151a28ab1b298b5759/html5/thumbnails/15.jpg)
Excimer lasers
Use reactive gases, such as
chlorine and fluorine, mixed
with inert gases such as argon,
krypton or xenon
![Page 16: Exploring laser systems - Zewail city](https://reader034.vdocuments.us/reader034/viewer/2022051404/58e821151a28ab1b298b5759/html5/thumbnails/16.jpg)
Dye lasers
In these lasers the lasing medium is made-up of one or a
mixture of gases or vapors. The most common of all gas
lasers is the helium-neon (He-Ne) laser
![Page 17: Exploring laser systems - Zewail city](https://reader034.vdocuments.us/reader034/viewer/2022051404/58e821151a28ab1b298b5759/html5/thumbnails/17.jpg)
Semiconductor lasers
Sometimes called diode lasers, are not
solid-state lasers. These electronic devices
are generally very small and use low power

Skin Care
• Removing inner layers of skin
• Hair removal
• Freckles removal
• Skin whitening

Fiber Optics
Fiber optics offer faster speeds of Internet connectivity as
compared to cable internet and DSL. Fiber optic cables
use signals transmitted by beams of laser light and suffer
from less signal degradation than copper cables.
