Importance of lasers in communication & advantages of fiber optics cables


The first laser eye surgery dates back to approximately 30 years. However, it is still considered to be a relatively new method of operating eye related disorders. Being aware of the advantages and disadvantages of laser eye surgery makes it easier for a patient to decide if it the procedure is going to suit him. Undergoing a laser eye surgery can be quite a daunting decision for many prospective patients. It may mainly be due to the apprehension in regards to the safety of their eyes, and lack of knowledge regarding the pros and cons of the surgery. So, what are the advantages and disadvantages related to laser eye surgery?

This difference allows lasers to focus light and energy on very small surfaces, even on far-away objects -- a unique characteristic that lends itself to various applications. Aside from their various applications, lasers are classified according to how they emit light. Their classification basis also stems from the medium or materials used as a source of light, whether gas, solid-state or diode lasers. A relatively recent development in laser technology, diode lasers use semiconductors -- usually microscopic Gallium-Arsenide chips -- as a medium. Laser printers, laser fax machines and supermarket bar code readers all use diode lasers. Using helium-neon lasers increases the size of these devices by as much as five times.

Metal fabrication refers to the processes and techniques required to design, create and assemble a metal structure. While welding — or using heat and pressure to fuse metal-based materials — is an essential component of the metal fabrication process for some projects, using the terms welding and metal fabrication interchangeably is like using the words fireplace and living room interchangeably. Laser Cutting Laser cutting is one of the most precise methods of cutting a design from a variety of different materials. The CNC machine, which does the cutting, is programmed to cut whatever design the client wants. From simple rectangles to precise, intricately designed pieces, laser cutting is your best option for most applications. CO2 Laser Cutting CO2 lasers are the highest-power continuous wave lasers that are available on the market. Because of their high power, they are ideal for cutting and boring.

The free electron laser uses a beam of relativistic electrons passing through a periodic, transverse magnetic field to produce coherent radiation. These devices have several advantages. A resonance condition that involves the energy of the electron beam, the strength of the magnetic field, and the periodicity of the magnet determines the wavelength of the radiation. Because one medium, the electrons, provides the gain in all spectral regions, adjusting either the beam energy or the field strength tunes the wavelength easily and rapidly over a wide range.

Laser diode cladding is a new technology that is becoming more refined and practical to use in modern industry. Although there are still many disadvantages to the technology. As you can see above laser diode cladding has many advantages and disadvantages in modern industry. The advantges of laser diode cladding will make cladding materials in industry more efficent and more feasable. You are commenting using your WordPress.

Communication in space. Laser communications systems are wireless connections through the atmosphere, The light speed is the fastest speed than anything can travel, so laser communications and laser sensing are important in mortar defense and other crucial aerospace and defense applications. Lasers are able to see through the dense foliage, and they can allow for space communication from distances measured in millions of miles, We use lasers everywhere such as in the military systems, the avionics and in submarines.
