Laser

LASER (Light Amplification by Stimulated Emission of Radiation) je optički izvor koji emituje fotone u dosljednom mlazu. Laserska zraka je obično skoro jednobojna, tj. sadržava jednu valnu dužinu ili nijansu, te se emituje u uskim mlazovima.

2. Pumpna energija lasera
3. Ogledalo
4. Djelomično ogledalo
5. Laserska zraka

Prvi upotrebljiv optički laser je napravio Theodore H. Maiman 1960 godine.

Koristi se u potrošačkoj elektronici i komunikacijama, astronomiji, nauci, medicini, industriji, vojsci i saobraćajnoj sigurnosti.
