Homann, C.; Bradler, M.; Förster, M.; Hommelhoff, P.; Riedle, Eberhard ORCID: 0000-0002-2672-5718 (2012): Carrier-envelope phase stable sub-two-cycle pulses tunable around 1.8 µm at 100 kHz. In: Optics Letters, Vol. 37, No. 10: pp. 1673-1675

We present a simple and efficient concept for the generation of ultrashort infrared pulses with passively stabilized carrier-envelope phase at 100 kHz repetition rate. The central wavelength is tunable between 1.6 and 2.0 µm with pulse durations between 8.2 and 12.8 fs, corresponding to a sub-two-cycle duration over the whole tuning range. Pulse energies of up to 145 nJ are achieved. As a first application we measure the high nonlinearity of multiphoton photoemission from a nanoscale metal tip.
