Laser Light Is Monochromatic And Coherent. Laser coherence unveiled1.1 2.1 the coherence. Lasers produce highly coherent, directional beams of monochromatic light. The basic structure of any laser is based on an active medium (either a gas or semiconductor) contained. Stimulated emission in lasers makes electrons produce a cascade of identical photons—identical in energy, frequency, wavelength—and that's why laser light is monochromatic. The photons produced are equivalent to waves of light whose crests and troughs line up (in other words, they are in phase)—and that's what makes laser light coherent. Contents0.1 1.1 invention and evolution0.2 1.2 understanding laser basics1 section 2: Different parts of the laser beam are related to each other in phase. 5.3.1 coherence of light sources; This means that laser light is both coherent and monochromatic. This is different from light that comes from other sources, such as light bulbs. This essentially follows from the light being monochromatic, and in fact the coherence time $\tau_{\mathrm{c}}$ is related to the frequency. Although light from a laser often has a very narrow band of frequencies and therefore can be considered to be monochromatic, purely monochromatic light does not exist. Characteristics of laser light 1. In the discussion so far we have only considered monochromatic light, which means that the spectrum of the light consists of only one frequency.
