Replica Pulse Compression Gratings

 View Grating List

HORIBA Jobin Yvon has traditionally provided master gratings for pulse compression applications, to ensure the highest optical performance and damage threshold. Master gratings are manufactured by HORIBA Jobin Yvon in both small and large dimensions.

We have also developed a very accurate replication process for producing high-quality and lower cost pulse compression gratings for less-demanding applications. This specific replication process is available for small size pulse compression gratings up to 110x110 mm in dimension.

All replica gratings for laser pulse compression are gold coated.
