Studies of the low- and high-order optical nonlinearities of mercury selenide quantum dots using femtosecond pulses

G. S. Boltaev et al.

Summary: The nonlinear optical properties of synthesized mercury selenide quantum dots (HgSe QDs) were investigated using near-infrared femtosecond pulses (1030 nm, 40 fs). Two-photon absorption in the HgSe QD suspension and third-harmonic generation using a 70-nm-thick HgSe QDs film were analyzed. The study also demonstrated high-order harmonics generation up to the 37th order in laser-induced plasmas containing HgSe QDs.

High-Order Harmonics Generation in MoS2 Transition Metal Dichalcogenides: Effect of Nickel and Carbon Nanotube Dopants

Mottamchetty Venkatesh et al.

Summary: Transition metal dichalcogenides, such as molybdenum disulfide (MoS2), with plasma state dopants, demonstrate the generation of intense high-order harmonics. MoS2 nanoflakes and nickel-doped MoS2 nanoflakes exhibit stronger harmonics compared to Mo bulk and MoS2 bulk. However, MoS2 with nickel nanoparticles and carbon nanotubes (MoS2-NiCNT) produces weaker coherent XUV emissions due to phase mismatch. The influence of heating and driving pulse intensities on harmonic yield and cut-off energies are investigated in MoS2 molecular structures.

High-order harmonics generation in nanosecond-pulses-induced plasma containing Ni-doped CsPbBr3 perovskite nanocrystals using chirp-free and chirped femtosecond pulses

Srinivasa Rao Konda et al.

Summary: This study demonstrates high-order harmonic generation and analyzes the harmonic properties by ablating nickel-doped CsPbBr3 perovskite nanocrystals using different types of pulses. The presence of nickel dopants and CsPbBr3 plasma components improves the emission of harmonics, and the spectral shift of harmonics generated from nickel-doped CsPbBr3 perovskite nanocrystals can be used to form tunable extreme ultraviolet sources.

Influence of embedded NiO-nanoparticles on the nonlinear absorption of tungsten disulfide nanolayers

Srinivasa Rao Konda et al.

Summary: In this work, the third-order nonlinear optical properties of pure tungsten disulfide (WS2) nanolayers decorated with NiO nanoparticles (NPs) were measured using femtosecond Z-scan measurements. The inclusion of NiO NPs increased the nonlinear absorption at 800 and 400 nm wavelengths. The nonlinear absorption mechanism of WS2 nanolayers can be switched from saturable absorption to two-photon absorption or reverse saturable absorption by changing the pump intensity with the embedded NiO NPs playing a crucial role.

Extension of high-order harmonic generation cutoff from laser-ablated tin plasma plumes

Wufeng Fu et al.

Summary: The high-order harmonic spectra from laser-ablated tin plasma plumes were studied experimentally and theoretically at different laser wavelengths. It was found that by decreasing the driving laser wavelength from 800 nm to 400 nm, the harmonic cutoff extends to about 84 eV and the harmonic yield is greatly improved. The Perelomov-Popov-Terent'ev theory, combined with semiclassical cutoff law and one-dimensional time-dependent Schrodinger equation, revealed that the contribution of Sn3+ ions accounts for the cutoff extension at 400 nm. Qualitative analysis of the phase mismatching effect showed that the phase matching caused by the dispersion of free electrons is greatly optimized in the 400 nm driving field compared to the 800 nm driving field. The high-order harmonic generated from laser-ablated tin plasma plumes driven by the short laser wavelength provides a promising way to extend cutoff energy and generate intensely coherent extreme ultraviolet radiation.

Three-color pump of laser-induced plasmas: sum and difference frequency generation

R. A. Ganeev

Summary: This study examines the generation of strong harmonics and sum and difference frequencies by propagating three pulses with different wavelengths and polarizations through Ag, Au, Pb, B, and C plasmas. The results demonstrate that difference frequency mixing is more efficient compared to the sum frequency mixing. Under optimal conditions for laser-plasma interaction, the intensities of the sum and difference components are almost equal to the intensities of neighboring harmonics attributed to the strong 806 nm pump.

High-order harmonic generation from a thin film crystal perturbed by a quasi-static terahertz field

Sha Li et al.

Summary: Studies have been mostly theoretical on laser-driven strong field processes under a (quasi-)static field, but this study provides experimental evidence by using a bichromatic approach for high harmonic generation (HHG) in a dielectric. The authors investigate the physics behind the THz field induced static symmetry breaking and its effects on even-/odd-order harmonics, and demonstrate the modulation of harmonic distribution as a way to probe HHG dynamics. They also report a delay-dependent frequency shift in even-order harmonics, suggesting limitations in the static symmetry breaking interpretation and opening opportunities in precise attosecond pulse shaping.

Summary: Intense high-order harmonics can be generated by phase- and polarization-structured femtosecond pulses. The strength of low-order harmonics varies with different driving beams (radially polarized beam, azimuthally polarized beam, and their superposition) in laser-induced plasmas. The phenomenon can be explained by phase matching and specific properties of vector beams.

Influence of chromium plasma characteristics on high-order harmonics generation

Vyacheslav V. Kim et al.

Summary: In this study, the method of laser-induced plasma formation and characterization is demonstrated for achieving efficient high-order harmonics generation during chromium ablation and propagation of femtosecond pulses through optimized plasma. The dynamics of chromium plasma spreading and the correlation between plasma velocities at different ablation regimes and the optimal delay of heating pulses and driving pulses are investigated. Laser-induced breakdown spectroscopy is used for optimizing the fluency of heating pulses and determining plasma parameters. The results show that the maximal harmonic yield is directly related to the optimization of plasma characteristics, particularly for the resonance-enhanced harmonics.

Distinction in resonance properties of the atomic and molecular contained plasmas used for high-order harmonics generation of ultrafast laser pulses

Rashid A. Ganeev et al.

Summary: This study reexamines the mechanism of resonance enhancement of a single harmonic during high-order harmonic generation in indium, zinc, and chromium-contained atomic and molecular plasmas. It was found that oxides, selenides, and phosphides of these metals notably reduce the enhancement of a single harmonic due to either a shift of the ionic transitions possessing strong oscillator strength out of the wavelength of those harmonics or a reduction of the oscillator strength of these transitions. The application of different wavelengths of driving pulses drastically changes the enhancement of a single harmonic in indium-contained plasmas.

Summary: Experimental results show that the presence of lead plasma does not hinder the enhanced harmonics in tin plasma, indicating that the macroscopic properties of the plasma are not responsible for the resonance-enhanced harmonics in tin. Enhanced harmonics at different wavelengths are observed in both pure tin plasma and tin/lead alloy plasma, attributed to resonances in singly-charged and doubly-charged tin ions.
