A key part of the Vulcan 10 PW OPCPA upgrade project is the grating specification for the final stretcher and compressor design. These gratings will need to satisfy a number of criteria. They should have large aperture > 0.6 m and be efficient across the 150 nm spectral bandwidth centred around 910 nm. Gratings with the required line density at the large aperture required are not readily available from any manufacturer. We have approached several large grating manufacturers and we are currently working with Plymouth Grating Laboratory (PGL) on the production and testing of small aperture grating samples with line density from 900 l/mm up to 1100 l/mm. Here we present resent results of the grating samples tests we have conducted.
