A high contrast dual OPCPA pre-amplifier system using both picosecond and nanosecond pump pulses for the Vulcan Petawatt Facility

View through CrossRef
We construct a dual OPCPA scheme with a picosecond OPA for seeding the Vulcan pre-amplifier demonstrating a 103 nanosecond contrast improvement. We provide evidence that the nanosecond contrast of this preamplifier is ~5*10−10.
