High-contrast near-IR short pulses generated by a mid-IR optical parametric chirped-pulse amplifier with frequency doubling.
We demonstrate the generation of high-contrast 1054nm short pulses based on a mid-IR optical parametric chirped-pulse amplifier with frequency doubling. Measurement-limited contrast higher than 10(9) is obtained over a large temporal range from approximately 100 ps to 3ps before the peak of the main pulse. With the potential of pulse-energy scalability, the demonstrated scheme incorporating further chirped-pulse amplification in the near-IR range is applicable to petawatt power-level laser systems.
