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.
