Generation of femtosecond laser pulse at 1053 nm with contrast ratio of 1011 by optical-parametric amplification

摘要

We demonstrated a high contrast 1053 nm femtosecond laser by exchanging the signal and idler in two stages non-collinear optical-parametric amplifier, 60 μI idler with measurement-limited contrast of 2.3×1011 was obtained within scale of sub-10 ps.
