Spatial solitons in quadratic 2D nonlinear photonic crystals [PDF]
, 2007 We report on the first investigations into parametric solitary-wave formation in 2D nonlinear photonic crystals and present experimental results obtained in an hexagonally poled LiNbO3 waveguide designed for twin-beam second harmonic generation at ...

Angle-resolved second harmonic generation for thin film characterisation [PDF]
EPJ Web of ConferencesWe present an all-optical method for the characterisation of thin centrosymmetric films based on second-harmonic generation (SHG), a nonlinear optical phenomenon sensitive to interfaces and symmetry breaking.

Enhanced resonant second harmonic generation in plasma based on density transition
Nukleonika, 2015 Resonant second harmonic generation of a relativistic self-focusing laser in plasma with density ramp profile has been investigated. A high intense Gaussian laser beam generates resonant second harmonic beam in plasma with density ramp profile.

General analysis of type I second-harmonic generation with elliptical Gaussian beams
, 1997 One can enhance second-harmonic generation in angle-tuned crystals by focusing the fundamental to an elliptical waist in the crystal. We present a general analysis for type I phase-matched uniaxial and biaxial crystals that will find particular ...

Optical second harmonic generation in encapsulated single-layer InSe
AIP Advances, 2018 We report the observation of optical second harmonic generation (SHG) in single-layer indium selenide (InSe). We measure a second harmonic signal of > 103 cts/s under nonresonant excitation using a home-built confocal microscope and a standard pulsed ...

Strong-field-assisted x-ray second harmonic generation
Physical Review ResearchWe theoretically demonstrate x-ray second harmonic generation (SHG) with strong-field-driven high harmonic generation (HHG) from core electrons in gas-phase atoms, highlighting its potential as a powerful spectroscopic tool for studying atomic and ...

Second-harmonic generation in SiC polytypes [PDF]
Physical Review B, 1998 LMTO calculations are presented for the frequency dependent second harmonic generation (SHG) in the polytypes 2H, 4H, 6H, 15R and 3C of SiC. All independent tensor components are calculated. The spectral features and the ratios of the 333 to 311 tensorial components are studied as a function of the degree of hexagonality. The relationship to the linear

Pediatric Blood &Cancer, EarlyView.ABSTRACT Febrile neutropenia (FN) is a frequent and serious complication in children receiving cancer therapy. Standardizing FN management across Asia is challenging due to variable healthcare infrastructure, diagnostic capacity, and infection patterns; however, it could improve resource use and patient outcomes.
