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.

How they're made. Our eyes can detect only a tiny part of the electromagnetic spectrum, called visible light. This means that there's a great deal happening around us that we're simply not aware of, unless we have instruments to detect it. Light waves are given off by anything that's hot enough to glow. This is how light bulbs work - an electric current heats the lamp filament to around 3,000 degrees, and it glows white-hot. The surface of the Sun is around 5,600 degrees, and it gives off a great deal of light.
