“…This approach would eliminate the need for the active pump-seed synchronization system for the OPCPA, because both the pump and the seed would travel comparable optical paths. In a cascaded gas-filled-HCF, the 1 ps input pulses centered at 1030 nm could be broadened to 700 − 1500 nm (Voronin et al, 2013). Although in this scheme the spectral phase in the vicinity of 1030 nm is not well-behaved and could cause a long pedestal in the time domain, the spectral phase in the blue and red wings of the spectrum are well-behaved and suitable for a type II DFG process.…”

Chirped pulse amplification in solid-state lasers is currently the method of choice for producing high-energy ultrashort pulses, having surpassed the performance of dye lasers over 20 years ago. The third generation of femtosecond technology based on short-pulse-pumped optical parametric chirped pulse amplification (OPCPA) holds promise for providing few-cycle pulses with terawatt-scale peak powers and kilowatt-scale-average powers simultaneously, heralding the next wave of attosecond and femtosecond science.OPCPA laser systems pumped by near-1-ps pulses support broadband and efficient amplification of few-cycle pulses due to their unrivaled gain per unit length. This is rooted in the high threshold for dielectric breakdown of the nonlinear crystals for even shorter pump pulse durations. Concomitantly, short pump pulses simplify dispersion management and improve the temporal contrast of the amplified signal.This thesis covers the main experimental and theoretical steps required to design and operate a high-power, high-energy, few-cycle OPCPA. This includes the generation of a broadband, high-contrast, carrier envelope phase (CEP)-stable seed, the practical use of a high-power thin-disk regenerative amplifier, its efficient use for pumping a multi-stage OPCPA chain and compression of the resulting pulses. A theoretical exploration of the concept and its extension to different modes of operation, including widely-tunable, high-power multi-cycle pulse trains, and ultrabroadband waveform synthesis is presented.Finally, a conceptual design of a field synthesizer with multi-terawatt, multi-octave light transients is discussed, which holds promise for extending the photon energy attainable via high harmonic generation to several kiloelectronvolts, nourishing the hope for attosecond spectroscopy at hard-x-ray wavelengths.

“…Therefore, the requirement for the control of these recurrent dynamics can be easily satisfied via the longitudinal adjustment of waveguide structures [22]. This can be done by either tapering the optical fiber along the propagation axis [23,24] or concatenating fibers with longitudinal tailoring properties [25,26]. In such a configuration, the quasi-stabilization evolution of breather waves can be realized using the technique based on the similarity between compressed breathers and fundamental solitons [27].…”

Manipulation of breather waves with split-dispersion cascaded fibers

A stabilization scheme is proposed for the dynamics of breather waves induced by the coherent-seed modulation instability based on manipulation of phase-space trajectory. Theoretical and numerical analysis show that carefully dispersion- and nonlinearity-managed cascades of fiber configuration allows the system evolution to be stabilized around an elliptic centre point, forming stable pulse trains with ultrahigh contrast efficiently. We also demonstrate that the scheme proposed works equally well for near-separatrix dynamics. Our results provide an alternative means to control the unsteady nonlinear waves by abruptly changing the waveguide properties.

“…Extremely short pulses were obtained in nonlinear optical fibers, both in the region of normal dispersion with the subsequent use of dispersion compressors [2][3][4], and in the region of anomalous dispersion due to multisoliton compression [5][6][7][8]. At a millijoule energy level, they were produced in gas-filled capillaries and photon-crystalline fibers due to the combined effect of ionization nonlinearity and plasma dispersion of group velocities [9][10][11][12]. A similar mechanism is realized by using filaments [13][14][15][16].…”

Self-compression of spatially limited laser pulses in a system of coupled light-guides

The self-action features of wave packets propagating in a two-dimensional system of equidistantly arranged fibers are studied analytically and numerically on the basis of the discrete nonlinear Schrödinger equation. Self-consistent equations for the characteristic scales of a Gaussian wave packet are derived on the basis of the variational approach, which are proved numerically for powers P < 10Pcr exceeding slightly the critical one for self-focusing. At higher powers, the wave beams become filamented, and their amplitude is limited due to nonlinear breaking of the interaction between neighbor light-guides. This make impossible to collect a powerful wave beam into the single light-guide. The variational analysis show the possibility of adiabatic self-compression of soliton-like laser pulses in the process of their three-dimensional self-focusing to the central light-guide. However, the further increase of the field amplitude during self-compression leads to the longitudinal modulation instability development and formation of a set of light bullets in the central fiber. In the regime of hollow wave beams, filamentation instability becomes predominant. As a result, it becomes possible to form a set of light bullets in optical fibers located on the ring.
