Plymouth Grating Laboratory

About Plymouth Grating Laboratory - PGL first commercialized the state-of-the-art Scanning Beam Interference Lithography (SBIL) technique pioneered at MIT to enable production of meter-class multilayer dielectric (MLD) diffraction gratings with exceptional uniformity, high laser damage threshold, and low stress in extreme conditions such as in vacuum. The company then expanded its technology to include metallic reflection gratings, transmission gratings, two­ dimensional gratings, and even focusing gratings that comprise curved lines. PGL gratings are used for pulse compression in the world's largest ultrahigh-intensity lasers as well as in compact, commercial femtosecond lasers, and for demanding metrology and spectroscopy applications. PGL products make a difference in the Scientific Research, Industrial (Materials Processing), Medical, and Analytical Instrumentation markets. The company occupies 20,000 sq. ft. of dedicated manufacturing, engineering, and office space in Carver, MA, just outside of Plymouth and about 45 miles south of Boston.
