“…For further investigations and applications of such phase-sensitive phenomena [11,12,[48][49][50][51][52][53][54], a single-cycle optical pulse, comprising only one cycle of the light oscillation, has been pursued in many laboratories. Different approaches include cascaded Raman sideband generation [55], broadband optical parametric amplification [56], and external compression [57][58][59]. To synthesize singlecycle pulses, several groups have worked on the synthesis of optical combs that span the visible to infrared ranges by synchronizing two broadband mode-locked lasers with different center wavelengths [40,60,61] or by synchronizing an optical parametric oscillator and its mode-locked pump laser [62,63].…”

We review our recent progress toward attosecondprecision ultrafast photonics based on ultra-low timing jitter optical pulse trains from mode-locked lasers. In femtosecond mode-locked lasers, the concentration of a large number of photons in an extremely short pulse duration enables the scaling of timing jitter into the attosecond regime. To characterize such jitter levels, we developed new attosecond-resolution measurement techniques and show that standard fiber lasers can achieve sub-fs high-frequency jitter. By leveraging the ultralow jitter of free-running mode-locked lasers, we pursued highprecision optical-optical and optical-microwave synchronization techniques. Optical signals spanning 1.5 octaves were synthesized by attosecond-precision timing and phase synchronization of two independent mode-locked lasers. High-stability microwave signals were also synthesized from mode-locked lasers with drift-free sub-10-fs precision. We further demonstrated the attosecond-precision distribution of optical pulse trains to remote locations via timing-stabilized fiber links. Finally, the application of optical pulse trains for high-resolution sampling and analog-to-digital conversion is discussed.The ultra-low timing jitter of optical pulse trains from femtosecond mode-locked lasers can be used for the attosecond-precision generation, distribution, measurement, and synchronization of optical and microwave signals.

“…Different cascaded spectral broadening techniques (e.g., doublefilamentation, hollow-core fiber (HCF) followed by a gascell), while having an intermediate pulse compressor have been used in these experiments. On the other hand, a double-HCF approach was reported by Schenkel et al [23], where generation of a broadband supercontinuum (500 THz) and compression of a part of it to produce 3.8-fs pulses was presented. However, in all the previous experiments (according to the best of our knowledge) characterization of such supercontinua in the NIR remained undiscussed.…”

We present the development of a light source for generating optically synchronized seed pulses both for the parametric amplifier chain and the pump-laser chain of the Petawatt Field Synthesizer (PFS), which is currently under construction at MPQ. The PFS system aims at delivering waveform-controlled few-cycle laser pulses with PW-scale peak power using optical parametric chirped pulse amplification (OPCPA). Methods of generating the broadband nearinfrared (NIR) seed pulses for the OPCPA chain by spectral broadening using few-cycle pulses are presented. We also demonstrate the generation of a supercontinuum spanning up to three octaves (270-1500 nm) using cascaded hollowcore fibers which supports sub-cycle pulse duration.

“…Actually, it is a real challenge to employ the effective dispersion compensation and return an isolated ultrashort optical pulse using the supercontinuum generation [17]. In the recent years, significant progress has been made in the generation of supercontinuum in the VIS-NIR spectral ranges, using hollow microstructured fibres or two gas-filled hollow fibres in a cascading configuration [18].…”

Abstract.We have achieved experimentally a generation of white-light few-cycle femtosecond laser pulses, using a neon-filled hollow-core fibre. The pulses observed by us are as short as 6.22 fs at the repetition rate of 1 kHz, when the input is characterized by the parameters 2.5 mJ and 33 fs. Pulse compression has been achieved using a supercontinuum produced in a static neon-filled hollow fibre, while a pair of chirped mirrors have compensated the dispersion. Our technique allows for directly tuning the pulse duration via changing the gas pressure, while maintaining near-transform-limited pulses with constant output energies and thus reducing the complications introduced by the chirped pulses. Using the measurements of the optical transmission of the fibre as a function of the gas pressure, we have testified a high enough throughput exceeding 60%. This demonstrates the successful compression that yields few-cycle femtosecond-long pulses, with a wide spectral bandwidth. The technique can be used when simultaneously exciting different states in complex molecules.
