The fiber route.According to PTG PTG - Missile-Armed Patrol Boat (US Navy) PTG - Paper Towel Guy (Dilbert comic) PTG - Parsons Transportation Group, Inc. PTG - Path to Glory (game) PTG - Perturbative-Type Green Function PTG - Piano Technician's Guild (trade association of piano tuners and technicians) PTG - Pietersburg, South Africa (Airport Code) PTG - Play The Game (online gaming) PTG - Portal-To-Go PTG - Premier Technology Group PTG - Professional Travel Grant Industries (Lake Mary, FL; www.ptgindustries.com) the use of fiber laser A laser that is constructed within an optical fiber. It is similar in concept to gas lasers and laser diodes, except that a part of the fiber itself is used as the resonating cavity where the laser action takes place. A laser diode is used as a pump, and mirrors accept the pump wavelength on one side and transmit the lased wavelength on the other. systems can provide a variety of advantages versus YAG YAG - Miscellaneous Auxiliary (Self-Propelled) YAG - Yttrium Aluminum Garnet or C[O.sub.2] systems for applications including marking, cutting and engraving. (The company offers a line of "FiberTower" Q-switched Fiber lasers for applications on materials including stainless steel, aluminum, carbide, polycarbonate, titanium, nickel, PVC, rubber, and chrome, including automotive applications ranging from creating the characters on turn signal stalks to making serial numbers on spark plugs.) Among the advantage that the company claims for the fiber systems: * Greater reliability: up to 100,000 hours mean time before failure * Reduced consumable costs * Reduced power consumption ($40/year at 170 W/hr) * Increased power efficiency (up to 50%) * Smaller spot size (50% of that produced by the other type). |
