Summary: CsPbBr3 nanoplatelets exhibit large optical nonlinearity, including third-order nonlinear absorption, refraction, and two-photon absorption excited luminescence. The nonlinear absorption cross section is two orders of magnitude larger than that of CsPbBr3 nanocrystals, making them suitable for optical limiting. Furthermore, they show large self-phase modulation-induced nonlinear refraction, allowing for optical switching.

Summary: The thickness-dependent saturable absorption behavior of atomically thin bismuth selenide films has been optimized using 515 nm and 1030 nm laser excitation wavelengths. The nonlinear optical parameters were determined as a function of film thickness through the use of Z scan technique.

Summary: We propose a method to extend the measurement capabilities of high power short pulse lasers by incorporating spectral sensitivity, specifically within the range used in chirped pulse amplification systems. The spectral response achieved through angle tuning of the third harmonic generating crystal is modeled and experimentally validated. Measurements of spectrally resolved pulse contrast of a Petawatt laser frontend illustrate the significance of full bandwidth coverage in interpreting laser target interactions, particularly with solid targets.

Summary: The combination of porphyrin and polyoxometalates has been shown to open new avenues in the field of optical materials. The synthesized looped covalently bonded Anderson-type polyoxometalate-porphyrin hybrids exhibited enhanced non-linear optical responses compared to their precursors. The integration of electron-accepting polyoxometalate moieties and electron-donating porphyrin moieties significantly enhanced the NLO response of the hybrids.

Summary: In this study, the nonlinear refractions of six different solvents were measured using a nonlinear ellipse rotation signal with femtosecond laser pulses. It was found that replacing hydrogen with deuterium atoms slightly reduces the nonlinearity, with toluene showing the greatest difference. The refractive nonlinearity was also observed to increase with longer pulse widths, and an empirical model was used to distinguish between electronic and orientational refractive nonlinearities of the solvents.

Summary: The study found that the aggregation of TPPS4 affects its excited-state lifetimes and quantum yields, but does not reduce the contact between the quencher and the excited aggregate. J-aggregates also do not change the contribution of energy transfer mechanisms to triplet state quenching by molecular oxygen. By producing singlet oxygen, having intense absorption in the phototherapeutic window, and efficiently converting light energy into heat, J-aggregates are considered a theranostic agent for photomedicine.

Summary: In this study, femtosecond-laser induced nonlinear ellipse rotation (NER) measurements were used to accurately determine the electronic nonlinear refraction, two-photon absorption spectra, and second-order hyperpolarizability of four azochromophores dissolved in methanol and acetone. The solvation effect of changing solvents from methanol to acetone was also reported. The results provide valuable information for all-optical switching applications.

Summary: We have investigated the polarization-resolved Z-scan technique to distinguish and discriminate between thermal, orientational, and ultrafast electronic nonlinearities simultaneously. By using a high-repetition-rate ultrafast laser, we excited these nonlinearities in pure and contaminated CS2 solvent and detected and measured the contribution of pure electronic, orientational, and thermal effects. The thermal effect was found to grow cumulatively as the laser repetition rate increases, and it was verified that the source of the thermal effect is mainly due to two-photon (one-photon) absorption for pure (contaminated) CS2.

Summary: We propose a single-beam method based on third-order nonlinear-ellipse-rotation (NER) measurement in thick samples to determine pulse properties. This method utilizes the intrinsic second-order dispersions of nonlinear materials to affect the NER signal as propagation function. The advantages of this method include the absence of a delay line and no phase-matching issues. We validated our method by characterizing ultrafast chirped pulses from a Ti:sapphire amplified laser system and tunable pulses from an optical parametric amplifier using SF6 and LaSF-N30 optical glasses.

Summary: Germanate glasses doped with AgNO3 and co-doped with AgNO3 and Au2O3 were synthesized, and the influence of Au2O3 addition on the nucleation and spectroscopic properties of the silver nanoparticles was investigated. Nonlinear ellipsometry technique was used to characterize the electronic contribution to the samples' nonlinear refraction and absorption, and the third-order nonlinear susceptibility was obtained for both the glass, composite samples, and individual nanoparticles. Additionally, the all-optical switching figures of merit were calculated for the samples.
