Laser light is monochromatic and coherent and the beam does not diverge significantly. White light is a mixture of all the colours and is not coherent.I don't know what you mean by 'stronger'. The energy density of a laser beam is greater than the energy density of a white light beam.Retsum Â· 7 years ago.hite light is a mixture of all the colours and is not coherent.

First, the light from a laser contains exactly one color or wavelength rather than a lot of different wavelengths. Scientists say that laser light is  monochromatic , meaning of one color. Flash is required to view this animation. Second, all the wavelengths are in phase.That is, they are all waving together, like a well-timed audience wave at a football game. All the wave crests (high points) and troughs (low points) are lined up. Scientists say the laser light is  coherent ..
