Directionality is the property of maintaining the direction of sound or light as it travels through space. A high directionality indicates that this direction is maintained to a high degree with small expansion.
Natural light is a collection of beams that propagate in every direction. To increase the directionality of natural light, complicated optical systems that eliminate all but the desired wavelength are necessary. Laser light has high directionality, making it easy to design optical systems that transmit the light over long distances without losing power.
