analysis of laser image in medical & Engineering application and its harmful effect on human eye Wavelengths of commercially available lasers. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the I. Introduction Fig1.

The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation.” A laser is different from other sources of light in that it emits light coherently1. Spatial coherence provides the advantage as a laser to be focused to a spot, enabling applications such as laser cutting and lithography. Lasers also have high temporal coherence, which allows them to emit light with a very narrow spectrum. They can emit a single colour of light. Temporal coherence can be used

Analysts forecast the Global Fiber Laser market to grow at a CAGR of 21.9 percent over the period 2013-2018. One of the key factors contributing to this market growth is the increasing adoption of fiber lasers due to their superior attributes. The Global Fiber Laser market has also been witnessing increased R&D spending by vendors in the market. However, the uncertainty in lifespan of fiber lasers could pose a challenge to the growth of this market. Global Fiber Laser Market 2014-2018, has been prepared

and technologies are already making their way into all aspects of dental practice and have changed the traditional approaches, which require that students and practitioners receive the necessary knowledge.1 Dental laser is one of the most significant developments in modern dentistry. Lasers were introduced into the field of Dentistry in 1960s, with the hope of overcoming some of the drawbacks posed by the conventional methods of dental procedures.2 Conventional methods of cavity preparation with low

descriptions of laser devices that have dental applications. The lasers are named according to their active medium, wavelength, delivery system, emission mode(s), tissue absorption, and clinical applications. The shortest wavelength is listed first. 101 Argon: Argon is laser with an active medium of argon gas that is energized by a high-current electrical discharge. It is fiber optically delivered in continuous wave and gated pulsed modes and is the only available surgical laser device whose light

Laser Resurfacing May Be The Solution For Your Acne Scars If you finally have your acne problem under control, but are left with a few scars on your face, you may want to consider letting a dermatologist remove them. One way to do that is with a laser resurfacing treatment. The laser is directed at your scars, so the rest of your skin is untouched. The treatment is fairly quick, but it does take a while for your skin to heal. Here is a quick look at this cosmetic procedure. Laser Resurfacing Erases

In the past, the applications of light, more specifically laser, in health and clinical applications have been focused on its destructive phototoxic effects. This effect is associated with high energy radiation, whereas low energy radiation has been found to induce a stimulating effect on the cells. The heat inducing laser tissue ablation effect used in surgery and the disinfectant-antimicrobial effect of light therapy are distinctly different from the beneficial healing response stimulated by photobiomodulation

target with a laser light. The name lidar, sometimes considered an acronym of Light Detection And Ranging,(sometimes Light Imaging, Detection, And Ranging), was originally a portmanteau of light and radar . Lidar is popularly used to make high-resolution maps, with applications in geodesy geomatics , archaeology geography, geology, geomorphology, seismology ,forestry atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. Lidar sometimes is called laser scanning

Lasers A laser is a gadget that transmits light through a procedure of optical intensification in view of the fortified outflow of electromagnetic radiation. The expression "laser" began as an acronym for "light enhancement by animated emanation of radiation". The first laser was implicit 1960 by Theodore H. Mailman at Hughes Laboratories, taking into account hypothetical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser varies from different wellsprings of light in that it emanates
