As regards energy content, laser emissions are not much strong. For example, a very powerful laser is used in entertainment shows, does not produce more light than an average streetlight. The only difference is how parallel it is. Light: “Light is normally emitted from atoms or molecules that meet with two conditions. They have stored energy originating from heat or previous absorption of light. A time has passed since the energy was stored. Light emitted in this way goes in random directions, with random phases and at random times.”(Welcher, 2000) “The light released is coherent. It is “organized” -- each photon moves in step with the others. This means that all of the photons have wavefronts that launch in unison. The light is very directional. A laser light then as a very tight beam and is strong and concentrated. A flashlight, on the other hand, releases light in many directions, and the light is very weak and diffuse.” (Weschler, 2000) When a comparison is made between visible light and laser as for the commercial use, the outreach of the laser is staggering. Visible light is nowhere in sight! In Medicine, “Lasers are used in microsurgical procedures such as making small, precise incisions, liver operations, and capillary surgery, causing little loss of blood. Lasers are also used to drill eyes in surgical needles. Ophthalmology - removal of cataracts and correcting vision n. Dermatology - removal of tattoos and skin lesions. Dentistry - filling cavities. Oncology - treatment of skin cancer.”
