Lecture 4-LASER Basic concept Properties

Lecture 4-LASER Basic concept Properties Lasers are special and different from other light sources due to coherence. Laser beams can be focused to very tiny spots. That’s why the laser gun is important. They can have very low divergence in order to concentrate their power at a great distance. Laser means light amplification by stimulated …
