A new technique, the self-recognition of feedback chirp compensation, which enables us to overcome problems in conventional optical pulse compression and generate a quasi-monocycle single pulse at a 1 kHz repetition rate, is introduced. The generation of a 1.5 cycle, 2.8 fs transform-limited pulse with a spectral broadening from 460 to 1060 nm is demonstrated. Furthermore, it is shown that the application of this technique for induced-phase modulated pulses enables us to generate 1.3 cycle, 2.6 fs optical pulses with a peak power of 1.4 GW. Finally, the future direction of the technology of such extremely short optical pulses is summarized briefly.
