"Broadband difference frequency mixing between visible and near-infrared pulses for few-cycle pulse generation with stable carrier-envelope phase" M. Bradler, C. Homann, and E. RiedleAppl. Phys. B 113, 19 - 25 (2013). Abstract: Difference frequency generation between broadband visible NOPA pulses and the fundamen-tal laser pulses allows the generation of ultrashort infrared pulses with passively stabilized carrier-envelope phase. A simple prism compressor for the visible NOPA pulses is sufficient to generate few-cycle pulses in the infrared and no additional compression is needed. We theoretically investigate the concept, explain the principles, and demonstrate it for high repeti-tion rate, long pulse durations, and various wavelengths by applying it to a Ti:sapphire and an Yb:KYW based laser systems. For the latter sub-15 fs phase-stable pulses around 1.8 µm with an energy of 100 nJ are obtained at 100 kHz repetition rate.
