Difference between Ordinary light and Laser light

Following are the major difference between Ordinary lights and Laser lights Laser light Ordinary light Laser lights are highly coherent Ordinary lights are incoherent in nature.. There coherence length as of the order of few km (Kilometer).

Properties of laser light

Coherence Laser light is highly coherent. All emitted photons have constant phase relationship i.e they are in same phase. The light from a laser is said to be coherent, which means the wavelengths of the laser light are in
