DIFFERENCES BETWEEN ORDINARY LIGHT AND LASER BEAM

Ordinary Light

1. In ordinary light the angular spread is more.

2. They are not directional

3. It is less intense.

4. It is not a coherent beam and is not in phase.

5. The radiations are polychromatic.

6. Egs: Sunlight, Mercury vapour lamp etc.

Laser beam

1. In laser beam the angular spread is less.

2. They are highly directional.

3. It is highly intense.

4. It is a coherent beam and is in phase.

5. The radiations are monochromatic.

6. Egs: He‒Ne laser, CO₂ laser etc.
