And laser light is coherent, which also makes it ideal for this application. Lasers are used in fiber optic communication systems because coherent light can be transmitted over much greater distances than incoherent light. The coherent laser light can be transmitted hundreds, even thousands of miles through fiber optic cables without much loss.

Definition and Properties of Laser Light | Environmental ...

The light from a laser is said to be coherent, which means the wavelengths of the laser light are in phase in space and time. These three properties of laser light are what make it more of a hazard than ordinary light. Laser light can deposit a great deal of energy within a very small area - as James Bond nearly found out in Goldfinger!

Are lasers coherent? - Quora

Two parallel slits lighted by a laser beam behind can be said to be two coherent point sources. Two independent monochromatic sources, emit waves of the same wavelength. ... So they are not coherent. This is because atoms cannot emit light waves in the same phase and these sources are said to be incoherent sources. Sarper Ozharar 6 y Related

Making coherent light from incoherent light. To sum up all of the above, you can start with an incoherently emitting lightbuld and mae into a coherent light source by: adding a spatial filter (pinhole - 'fixing' the spatial coherence), and; adding a frequency filter ('fixing' the temporal coherence), as shown below.

Why laser light is coherent | Physics Forums

All kinds of light will have some coherence time. It might be in the fs range (sunlight) or in the second range for lasers or number-squeezed light. Drawing a line somewhere and saying "light is coherent if it has a minimal coherence time of XYZ" would be rather arbitrary and not satisfying.

what is coherent light | Laser Pointer Forums - Discuss Laser ...

The laser emission is phase aligned so you always see the intensity at . Considering it have the same frequency and go at the same direction, you have a coherent light. In a LED you dont have the phase alignment. The light is a superposition of different phases, leading to a mean of intensity. Besides, the propagation is "isotropic".

Laser pointers are not low level laser therapy systems

True Low Level Laser Therapy (LLLT) requires a very specific type of laser. It must use a wavelength (color) of exactly 635-nm (nanometer). Then it must be powered at less than 5mW (less than 5 thousands of one watt). Then it must be a true laser which produces collimated coherent light. Coherent light is where all of the photons are in phase ...
