“…5, right), which produces CEP-stable pulses via nonlinear frequency conversion. We refer the readers seeking to familiarize themselves with the working of a CEP-stable oscillator to several excellent reviews on the subject [2,3,45,46] and recommend further reading on more recent advances, such as direct CEP locking from an octave-spanning Ti:sapphire oscillator [47][48][49], CEP locking to a DFG beat signal [50], full repetition rate CEP stabilization [51][52][53].…”

“…A major advantage of this feedforward approach is that the bandwidth is only limited by the bandwidth of the AOFS, which allows one to achieve much higher bandwidths than in traditional feed-back servo-loops. Alternatively, one can place the AOFS in one of the arms of the f -to-2 f interferometer, shifting one of the combs by the modulation frequency ω m ; this allows setting ω CE to zero without incurring the 1= f noise problem [40,53].…”

One of the most advanced frontiers of ultrafast optics is the control of carrier-envelope phase (CEP) φ of light pulses, which enables the generation of optical waveforms with reproducible electric field profile. Such control is important for pulses with few-optical-cycle duration, for which a CEP variation produces a strong change in the waveform, so that strongly nonlinear optical phenomena, such as multiphoton absorption, above-threshold ionization and high-harmonic generation become CEP-dependent. In particular, CEP control is the prerequisite for the production of isolated attosecond pulses. Standard laser systems generate pulses that are CEP unstable; the CEP can be stabilized using either active or passive methods. Passive, all-optical schemes rely on differencefrequency generation (DFG) between two pulses sharing the same CEP: in this process the phases of the two pulses add up with opposite signs, leading to cancellation of the shot-to-shot CEP fluctuations. This paper presents an overview of passive CEP stabilization schemes, starting from the basic concepts and progressing to the details of the practical implementations of the idea. The passive approach allows the generation of CEP-controlled few-optical-cycle pulses covering a very broad range of parameters in terms of carrier frequency (from visible to mid-IR), energy (up to several mJs) and repetition rate (up to hundreds of kHz).

“…pulses so short that the pulse envelope encloses only a few cycles of the field, have become indispensable tools in optics and related sciences, such as High-order Harmonic Generation (HHG) [1], attosecond science [2], strong-field physics [3], and acceleration of particles [4]. While low-energy, few-cycle pulses can today routinely be obtained from Titanium:Sapphire (Ti:Saph) based ultrafast oscillators [5], the output of chirped pulse amplification (CPA) femtosecond lasers hardly reaches below 20 fs pulse duration, mostly due to gain-bandwidth-narrowing. Typical Ti:Saph based CPA lasers, found in research laboratories today, have pulse duration in the range of 25-100 fs and pulse energies in the mJ to hundreds of mJ range.…”

Compression of TW class laser pulses in a planar hollow waveguide for applications in strong-field physics

Abstract. We demonstrate pulse post-compression of a TW class chirped pulse amplification laser employing a gas-filled planar hollow waveguide. A waveguide throughput of 80% is achieved for 50 mJ input pulse energy. Good focusability is found and after compression with chirped mirrors a pulse duration of sub-15 fs is measured in the beam center. Whereas a total energy efficiency of ≈70% should be achievable, our post-compressor currently delivers 20 mJ output pulse energy (≈40% efficiency), mostly limited by apertures of chirped mirrors and vacuum windows. The viability of the planar hollow waveguide compression scheme for applications in strong-field physics is demonstrated by generating high-order harmonics in a pulsed Ar gas cell.

“…However, the PLL cannot be directly employed to stabilize f CEO at zero because the PLL needs a carrier to detect the error signal. Some approaches have been reported for achieving an offset-free comb, namely, shifting f CEO with an acousto-optic modulator (AOM), 7) using feed-forward controls to cancel f CEO with an AOM, [8][9][10] employing carrier envelope phase controls via optical parametric processes 11) and difference frequency generation. 12,13) The last two methods need a rather complicated system with nonlinear processes that require very intense optical pulses.…”

We demonstrate an erbium-based offset-free frequency comb using a fiber-coupled acousto-optic modulator. The comb has two f–2f interferometers; one is for carrier-envelope offset beat detection, and the other is for frequency-shifted offset beat detection. The frequency was shifted by placing the acousto-optic modulator in front of an amplifier and a highly nonlinear fiber for spectral broadening. We confirmed that the offset frequency was stabilized at zero and measured it by shifting it from zero. The Allan deviations of the measured offset frequency were 0.10 and 0.18 Hz with a 1 s averaging time and using feedback and feed-forward stabilization, respectively.
