With the emergence of high repetition rate few-cycle laser pulse amplifiers, e.g. for high-harmonic generation and the investigation of rare events in atomic and molecular science, the need for fast carrier-envelope phase (CEP) detection and control has arisen [1]. Here, we demonstrate an ultrafast detection and feedback scheme based on a stereo above-threshold ionization time-of-flight spectrometer (stereo ATI) capable of detecting the CEP and pulse duration at a repetition rate of up to 400 kHz [2]. It is applied to a 100 kHz, 200 µJ pulse energy NOPA laser system that is seeded by a Ti:Sa oscillator [3].
