# IPG Photonics

> IPG Photonics is a Massachusetts-based manufacturer of high-power fiber lasers and amplifiers headquartered in Oxford, Massachusetts, founded in 1990 by Valentin Gapontsev, whose research on rare-earth-doped fiber amplifiers provided the scientific foundation for the company. IPG pioneered the commercialization of high-power ytterbium (Yb), erbium (Er), and thulium (Tm) fiber lasers that have become the dominant technology in industrial laser materials processing, displacing CO2 and solid-state lasers in cutting, welding, brazing, and surface treatment applications. For researchers, IPG provides tunable and pulsed fiber laser sources covering wavelengths from ultraviolet to mid-infrared for applications in laser spectroscopy, atmospheric sensing, and materials science experiments. Their femtosecond fiber lasers (YLMO series) deliver ultrashort pulses for precision micromachining of glass, ceramics, biological tissues, and transparent materials in laboratory and translational research settings. IPG's mid-infrared fiber lasers in the 1.5-4.5 μm range enable molecular fingerprint spectroscopy and trace gas sensing. Their amplifier modules are used to boost pulsed laser sources in research setups requiring high peak power. The company's photon delivery systems, beam combiners, and process heads are engineered for integration into custom research instruments and pilot manufacturing lines. IPG's green and UV fiber laser products address applications in semiconductor inspection, ophthalmology research, and fine-feature microfabrication at research institutions.
