2. Light Amplification by Stimulated Emission of Radiation
A LASER is a device that generate an intense beam of
coherent monochromatic light.
Widely used in Opthamlogoy and neurology
LASER
 Spatial ( same phase)
 Temporal Coherence
 Monochromatic wavelength
 Highly directional
 High density energy
 Tunable and finely focused

4. TYPES OF
LASER
Types of Emission:
There are two types of Emission;
Stimulated Emission:
It is the process by which an incoming photon of a specific frequency can
interact with an excited atomic electron.
Spontaneous Emission:
A Quantum effect causing the spontaneous decay of excited states of
atoms and ions.
