Many scientific‚ military‚ medical and commercial laser applications have been developed since the invention of the laser in the 1958. The coherency‚ high monochromaticity‚ and ability to reach extremely high powers are all properties which allow for these specialized applications. Scientific In science‚ lasers are used in many ways‚ including: A wide variety of interferometric techniques Raman spectroscopy Laser induced breakdown spectroscopy Atmospheric remote sensing Investigating nonlinear

it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity‚ or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical amplifiers. In doped fiber amplifiers and bulk lasers‚ stimulated emission in the amplifier’s gain medium causes amplification

Adamac must be conscious of their internal strengths to ensure they are able to maintain their position in the industry. A SWOT analysis can be viewed in Exhibit 1. Adamac currently has over 70 clients and is operating at full capacity. Adamacs’ laser cutter machine broke down 6 times last year‚ and the water jet machine broke down 5 times. The total cost of outsourcing this work was $10‚500‚ the cost breakdown can be view in Exhibit 2. Quality control of their product is a

fiber‚ Free Space Optics (FSO) uses lasers to transmit data‚ but instead of enclosing the data stream in a glass fiber‚ it is transmitted through the air. Free Space Optics (FSO) works on the same basic principle as Infrared television remote controls‚ wireless keyboards or wireless Palm® devices. How Free Space Optics (FSO) Works Free Space Optics (FSO) transmits invisible‚ eye-safe light beams from one "telescope" to another using low power infrared laser in the terahertz spectrum. The beams

FIBER-OPTIC COMMUNICATION Introduction Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic waves that is modulated to carry information. First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical
