How to Choose the Right Diffraction Grating for Pulse Compression

Diffraction gratings are critical components for most Chirped Pulse Amplification (CPA) laser systems. There are many different grating types (metal, all-dielectric, and hybrid metal-dielectric reflection gratings, as well as transmission gratings), and equally as many trade-offs relating to diffraction efficiency, spectral and angular bandwidth, polarization, laser-induced damage threshold (LIDT), and temporal dispersion, to name a few. Choosing the right grating for a given laser system can be very confusing. In this webinar we will describe how you can make the best grating selection for your laser requirements.

PGL Launches Nonpolarizing MLD Diffraction Gratings for Directed Energy

February 23, 2023 | In the News

Plymouth Grating Laboratory (PGL), the leading commercial manufacturer of large, high-performance diffraction gratings for lasers and laser systems, announced that it has launched a new product line for Spectral Beam Combining (SBC) of High Energy Lasers (HEL) used in Directed Energy applications. »

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.
