Abstract:A new front-end laser system with optical synchronization of chirped
femtosecond and pump pulses for the petawatt laser complex PEtawatt
pARametric Laser (PEARL) has been developed. The new front-end system
provides a broader femtosecond pulse spectrum, temporal shaping of the
pump pulse, and a significant increase in the stability of the
parametric amplification stages of the PEARL.
“…[44,45], with the help of supercontinuum generation, the beam is converted into the wavelength band of 700–1000 nm with a Fourier-transform-limited pulse duration of several cycles and with passive stabilization of the field phase relative to the envelope, also known as CEP-stability. Experiments [ 46 ] showed the possibility of generating laser pulses with a duration of 20 fs in the band of parametric amplification in a DKDP crystal (Figure 4). Figure 4 Measured pulse intensity and phase at the output of a parametric amplifier based on a BBO crystal [ 46 ] .…”

The eXawatt Center for Extreme Light Studies project aimed to create a large scientific infrastructure based on lasers with giant peak power. The project relies on the significant progress achieved in the last decade. The planned infrastructure will incorporate a unique light source with a pulse power of 600 PW using optical parametric chirped pulse amplification in large-aperture KD 2 PO 4 , deuterated potassium dihydrogen phosphate crystals. The interaction of such laser radiation with matter represents a completely new fundamental physics. The direct study of the space-time structure of vacuums and other unknown phenomena at the frontier of high-energy physics and the physics of superstrong fields will be challenged. Expected applications will include the development of compact particle accelerators, the generation of ultrashort pulses of hard X-ray and gamma radiation for material science enabling one to probe material samples with unprecedented spatial and temporal resolution, the development of new radiation and particle sources, etc. The paper is translation from Russian [Kvantovaya Elektronika 53, 95 (2023)].

A proof-of-principle experiment of highly efficient (38%) second harmonic generation was implemented at a ∼1TW/cm2 intensity of a 45 fs pulse in a composite nonlinear sample–a 1 mm KDP crystal glued onto a 1 mm fused silica substrate. The attenuated replica of the second harmonic pulse (455 nm) was compressed down to 28.6 fs by means of dispersive mirrors, with a significant reduction in both the wings and the far temporal contrast. The peak power of the second harmonic was ∼74% of the power of the fundamental harmonic, which ensured a three-fold increase in the focal intensity.
