IPG Photonics Corporation develops and manufactures a range of high-performance fiber lasers, fiber amplifiers, and diode lasers used in various applications, primarily in materials processing worldwide. The company's laser products include low, medium, and high power lasers; fiber pigtailed packaged diodes and fiber coupled direct diode laser systems; high-energy pulsed lasers, multi-wavelength and tunable lasers, and single-polarization and single-frequency lasers; laser diode chips and packaged laser diodes; and high power optical fiber delivery cables, fiber couplers, beam switches, chillers, scanners, and other accessories. It also provides erbium-doped fiber and Raman amplifiers, and integrated communications systems, which are deployed in broadband networks, such as fiber to the home, fiber to the curb, passive optical networks, and dense wavelength division multiplexing (DWDM) networks; ytterbium and thulium specialty fiber amplifiers and broadband light sources; and single-frequency, linearly polarized, and polarization-maintaining versions of its amplifier products. In addition, the company offers interconnect, coarse wavelength division multiplexing, DWDM, and tunable-based pluggable interfaces to serve optical transmission needs; integrated laser systems; 2D flat sheet cutter systems and multi-axis systems; welding seam stepper and picker, a fiber laser welding tool for use in automotive, appliances, rail cars, and other sheet metal fabrication; and specialized fiber laser systems for material processing applications. Its lasers and amplifiers are also used in materials processing, advanced communications, and medical applications. The company markets its products to original equipment manufacturers, system integrators, and end users through direct sales force, as well as through agreements with independent sales representatives and distributors. IPG Photonics Corporation was founded in 1990 and is headquartered in Oxford, Massachusetts.
