N2 - The picosecond contrast is an outmost parameter for multi-PW laser systems. The presence of tens of picosecond pedestal prior to the main pulse in multi-PW class laser system could lead to damage of the target as it can reach intensity on target higher than 1014W/cm2. It has been demonstrated that the convex mirror within the Offner stretcher of those laser systems is the main contributor to this pedestal [1]. To reduce this effect, ultralow roughness mirrors have been implemented in some laser systems [2].
