Properties of laser
Laser light is monochromatic, directional and coherent
- Monochromatic - means of one wavelength. In contrast, ordinary white light is a combination of different wavelengths.
- Directional- laser light is emitted as a narrow beam and in a specific direction. This property is referred to as directionality.
- Coherent - The light from a laser is said to be coherent. This means that the wavelengths of the laser light are in phase.
