(sub-8 cycle) pulses with 44 μJ pulse energy at 160 kHz repetition rate and excellent beam
quality (M2<1.4). … Here, we present a new approach which leverages chirp inversion within the
OPCPA chain to achieve few-cycle, self-CEP stable mid-IR pulses reaching an unprecedented
compressed pulse energy of 44 µJ at 160 kHz. … We report a unique, few-cycle, self-CEP
stable, mid-IR OPCPA system which leverages chirp reversal to deliver a record compressed …
