White-light-seeded, CEP-stable, 4.5-W, 4-micron KTA parametric amplifier driven by a 1.4-ps Yb:YAG thin disk laser

Tsuneto Kanai, Yeon Lee, Meenkyo Seo +1

We demonstrate a robust, carrier envelope phase (CEP)-stable, potassium titanyl arsenate (KTA)-based optical parametric amplifier (OPA) delivering 6-cycle (79 fs), 3.8-$\mu$m pulses…
