Carrier-envelope phase-dependent high harmonic generation in the water window using few-cycle infrared pulses
High harmonic generation (HHG) using waveform-controlled, few-cycle pulses from Ti:sapphire lasers has opened emerging researches in strong-field and attosecond physics. However, the maximum photon energy of attosecond pulses via HHG remains limited to the extreme ultraviolet region. Long-wavelength light sources with carrier-envelope phase stabilization are promising to extend the photon energ...
متن کاملGeneration and characterization of few-cycle mid-infrared pulses from 2800 to 4600 nm
Sub-five-cycle pulses in the spectral region from 2800 to 4600 nm are generated using a potassium niobate optical parametric amplifier employing a germanium pulse compression scheme. The sub-65-fs mid-infrared pulses are fully characterized by XFROG. 2002 Optical Society of America OCIS codes: (320.7110) Ultrafast nonlinear optics; (190.4970) parametric oscillators and amplifiers. Generation o...
متن کاملHigh harmonic generation with long-wavelength few-cycle laser pulses
We report the extension of hollow-core fibre pulse compression to longer wavelengths. High-energy multi-cycle infrared pulses are generated via optical parametric amplification and subsequently broadened in the fibre. 2.5-cycle pulses at the Signal wavelength (1.4 μm) and 1.6-cycle pulses at the Idler wavelength (1.8 μm) in the sub-millijoule regime have been generated. New compression schemes ...
متن کاملMulti-millijoule few-cycle mid-infrared pulses through nonlinear self-compression in bulk
The physics of strong-field applications requires driver laser pulses that are both energetic and extremely short. Whereas optical amplifiers, laser and parametric, boost the energy, their gain bandwidth restricts the attainable pulse duration, requiring additional nonlinear spectral broadening to enable few or even single cycle compression and a corresponding peak power increase. Here we demon...
متن کاملGeneration of Phase-Stable Sub-Cycle Mid-Infrared Pulses from Filamentation in Nitrogen
Sub-single-cycle pulses in the mid-infrared (MIR) region were generated through a laser-induced filament. The fundamental (ω1) and second harmonic (ω2) output of a 30-fs Ti:sapphire amplifier were focused into nitrogen gas and produce phase-stable broadband MIR pulses (ω0) by using a four-wave mixing process (ω1 + ω1 − ω2 → ω0) through filamentation. The spectrum spread from 400 cm−1 to 5500 cm...
