We demonstrated a high contrast 1053 nm femtosecond laser by exchanging the signal and idler in two stages non-collinear optical-parametric amplifier, 60 uJ idler with measurement-limited contrast of 2.3×10 was obtained within sub-10 ps.
We generated laser power of 1.16PW from a Ti:sapphire laser facility by using a combined scheme of doubled chirped-pulse amplifier (DCPA) and non-collinear optical parametrical amplifier (NOPA). Laser energy up to 32.3J was obtained with the pulse duration was 27.9fs. By clean high-energy seeding pulse injection from the NOPA stage, contrast ratio of the main amplified laser pulse was improved to...
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.
We generated 32.3J laser pulse at 27.9fs from a Ti:sapphire laser facility based on chirped-pulse amplification with optical parametrical amplified femtosecond laser as new seeding, result in peak power of 1.16 PW with high contrast.
