Abstract

We compressed high-power laser pulses to 5 fs and 0.5 mJ using a neon-filled hollow-core fiber and a high-throughput 4f system. The carrier–envelope phase of the two-cycle pulses was measured directly by using their over-one-octave output spectrum. The carrier–envelope phase was stabilized by feedback controlling the grating separation of a stretcher in a chirped pulse amplifier. To the best of our knowledge, this is the first time that carrier–envelope phase locked few-cycle pulses were generated by using an adaptive phase modulator.
