PGL designs and manufactures the best diffraction gratings specifically for 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. They are designed exactly to our customers’ requirements. This performance and flexibility are made possible by PGL’s exclusive use of the most flexible large grating manufacturing sytsem available – the Nanoruler – based on the proprietary Scanning Beam Interference Lithography technology developed at MIT, and PGL’s industry-leading process expertise.
We know what it feels like when your laser, system, or manufacturing line is down due to a late or failed grating and you can’t get help or even a response. Our team has supported the world’s largest lasers and laser facilities for decades, yet also has decades of experience supplying optics to the most demanding OEM customers. And with our combined expertise in gratings and thin-film coatings, PGL is the leading manufacturer of multilayer dielectric (MLD) gratings.
