Properties of Laser Light
Laser Light has three very different properties from normal light.
Laser light is monochromatic, meaning it contains a single colour of a narrow range of colours. The wavelength is determined by how much energy is released when the electron moves down to a lower energy level.
Laser light is also collimated which means the light is very directional and doesn’t release light in many directions but in a tight beam that is strong and concentrated.
Thirdly laser light is coherent, each photon moves in phase with the others. Ordinary light however is comprised of a combination of frequencies that are considered out of step with each other.
