The qualities of the light generated by a laser are significantly different from that generated by a conventional source such as an incandescent light bulb or fluoresce light tube. These major differences include: divergence: the laser generally emits a pencil thin beam of light whose divergent angle closely related to the wavelength and limiting aperture size. bandwidth: the light emitted by the laser generally consists of a very narrow range of wavelengths, or color. intensity: the output from a laser is typically orders of magnitude higher in intensity (measured in watts per square meter) than a conventional light source. coherence; the output from a laser is generally coherent; that is, the peaks and troughs of the light waves all correspond, allowing the light to form clear interference patterns.**
