title: High-temporal-quality injector generated by optical parametric amplification with hollow-core-fiber compression.
abstract: We demonstrate a 100 μJ, <10 fs, high-temporal-contrast injector. The experimental setup is based on an optical parametric amplification system followed by a standard hollow-core-fiber compressor and a frequency-doubling crystal. Pulses near 800 nm with FWHMs of about 160 nm are generated. More than 11 orders of magnitude of the contrast ratio, which is limited by the measurement device, are obtained over a large temporal range extending from <1 ps ahead of the main pulse. The broad spectral bandwidth and the high contrast of this device make it a good front-end injector for a few-cycle, high-power laser system.
