White light is a mixture of many waves of different links called frequency, it's like Musical Instruments playing different notes, but the light from a laser contains waves of one light only which make a single color.

Laser light is a narrow beam of light but regular light is not a narrow beam of light.

-----

The term laser is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser beam is a powerful, narrow, monochromatic and directional beam of electromagnetic radiation. Often, these beams are within the visible spectrum of light. A laser device excites the atoms in a lasing medium. The electrons of these atoms move to a higher orbit, then release photons, creating a laser light.

Light is really an electromagnetic wave. Each wave has brightness and color, and vibrates at a certain angle, so-called polarization. This is also true for laser light but it is more parallel than any other light source. Every part of the beam has (almost) the exact same direction and the beam will therefore diverge very little. With a good laser an object at a distance of 1 km (0.6 mile) can be illuminated with a dot about 60 mm (2.3 inches) in radius.It can also be made very monochromic, so that just one light wavelength is present. This is not the case with ordinary light sources.Alternatively check out this website, for copy-and-pasted answers...

Ordinary light Vs Laser light

Ordinary light:

1. multi chromatic or monochromatic. Though monochromatic it is not coherent

2. Diverging

3. Less intense

Laser light:

1. Only monochromatic

2. Coherent

3. Non diverging

4. Highly intense.

Laser light is coherent and monochromatic, whereas natural light is not coherent and is polychromatic.

.

Monochromatic means all the light is an exact color - in fact, an exact wavelength, whereas natural white light comprises a random assortment of all colors (all visible wavelengths). Non-laser light is almost never monochromatic, although colored filters can be used to reduce natural light to a narrow range of wavelengths in a specific region of the spectrum.

.

Coherent means all the light waves are in perfect phase as they pass through any point. Coherent waves do not interfere with each other as they travel, and therefore coherent waves can travel over great distances.

Laser light is different in two main aspects.* It is monochromatic, i.e., all the light has the same frequency (or color).

* It is in phase - all the individual pieces of light have their maximum at the same time.

How can you tell the difference between a laser and a beam of white light?

A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).

Is it possible to create white colored laser?

It is, but you have to use an red, blue and green laser. White light is a mixture of different wavelenght's en thus cannot be created with a single laser


What is the difference between a black light bulb and white light bulb?

Light is available in a variety of wavelengths depending on the emitter. Black light is in the ultraviolet range. White light is a mixture of frequencies in the visible range.

How laser pointers work?

Laser lights have certain characteristics that allow it to seperate from regulare white light. The light is colored because it is organized light. It also contains a specific wavelength which produces the colored light.


A good example of white light?

White light is another name for polychromatic light. That is light that contains more than one wavelength. For example, sunlight is white light. An example of monochromatic light is a sodium vapour lamp or a LASER.
