Plymouth Grating Laboratory chosen by French research giant CEA

September 01, 2016 | In the News
Plymouth Grating Lab, a leading manufacturer of meter-class, high-performance diffractiong gratings, announced that it was awarded a major multiyear contract to supply the French Commission for Atomic Energy and Alternative Energies (CEA) with state-fo-the-art transmission gratings for its Megajoule Laser (MLJ) facility.... READ MORE »
Plymouth Grating Laboratory is dedicated to making the highest-quality diffraction gratings available today. Our focus is on lasers and laser systems. PGL gratings offer exceptionally high diffraction efficiency and laser damage threshold, combined with superior wavefront error and uniformity over large areas. This performance is made possible by PGL’s exclusive use of the Nanoruler, based on the proprietary Scanning Beam Interference Lithography technology developed at MIT, and PGL’s industry-leading process expertise. 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.
