 cladding. Historically, machine tools such as grinding machines, mechanical saws, milling machines, lathes, presses, water jet cutters, plasma cutters and welding machines have been used to cut, join, form or otherwise process metal in the production of finished goods such as automobiles, consumer appliances, electronics and heavy machinery. Also, lasers are utilized in applications that require consistent and stable operation with lower power densities, such as heating, cleaning and drying. Laser-based systems are gaining share within the materials processing market because of the greater precision, processing speeds and flexibility enabled by this technology. Beyond materials processing, lasers are well-suited for imaging and inspection applications and the ability to confine laser light to narrow wavelengths makes them particularly effective in medical, non-destructive inspection and sensing applications. 

Fiber Lasers

Fiber lasers use semiconductor diodes as the energy source to pump a gain medium consisting of specialty optical fibers, which are infused with rare earth ions. These fibers are called active fibers and are comparable in diameter to a human hair. The laser emission is created within optical fibers and delivered through a flexible optical fiber cable. As a result of their different design and components, fiber lasers are more reliable, efficient, robust, compact and easier to operate than gas, crystal and solid state lasers that were initially used in industrial applications. In addition, fiber lasers free the end users from fine mechanical adjustments and the high maintenance costs that are typical for other laser technologies. 

Although low power fiber lasers were introduced four decades ago, their increased adoption in the last twenty years has been driven primarily by our improvements in their output power levels and cost, as well as their superior performance, lower cost of ownership and greater reliability compared with other laser and non-laser technologies. We successfully increased output power levels, efficiency and reliability by improving optical components such as diodes and active fibers that increased their power capacities and improved their performance. Fiber lasers now offer output powers that exceed those of other laser technologies in many categories. Our substantial advancements in diode technology, packaging design and other optical components together with increased production volumes over the last two decades reduced the cost and increased the reliability

of our products. As a result, the average cost per watt of output power has decreased dramatically and our fiber lasers effectively compete in many applications that used other laser technologies and non-laser solutions historically. We believe that fiber lasers provide a combination of benefits that include: superior performance; enhanced end user productivity; lower cost of ownership and environmentally friendly operation; greater
