Efficient Enhancement of Second Harmonic Generation via Noninvasive Modulation

Applied Sciences, 2022
Second harmonic generation has been widely applied in various fields. High second harmonic intensity can facilitate optical imaging, signal sensing, and detection. Thus, enhancing the intensity of the second harmonic is a significant work.

Second-harmonic generation from singular metasurfaces

, 2022
We present a theoretical study of second-harmonic generation from a singular metasurface. The singular metasurfaces strongly interact with the incident light, where the large field enhancement forms an intense surface polarization that generates the ...

Angle-resolved second harmonic generation for thin film characterisation [PDF]

EPJ Web of Conferences
We 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.

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 ...

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.

Second Harmonic Generation in a Photonic Crystal [PDF]

Optics and Photonics News, 1997
Phase matched second harmonic generation is observed experimentally in a centrosymmetric crystalline lattice of dielectric spheres of optical dimensions. The inversion symmetry is broken locally at the surface of each sphere in such a way that the scattered second harmonic light interferes constructively leading to a nonvanishing macroscopic field ...

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.
