UPHILL houses two state-of-the-art intense laser facilities – (a) a 20 terawatt and (b) an ultrahigh-contrast 100 terawatt chirped-pulse-amplified titanium-doped sapphire laser, that deliver joule-energy pulses of 30-femtoseconds pulsewidth centered at a wavelength of 800 nm and operating at a repetition rate of 10 Hz. The peak intensities that can be generated are typically 1018...
