Abstract The giant bulk photovoltaic effect in tellurene nanomaterials has been harnessed to enable broadband infrared neuromodulation, expanding the potential for safe, non-invasive neural stimulation and highlighting importance of material innovation advancing photonic applications.
We successfully prepared a series of optically poled germanosilicate glass. As second harmonic generation (SHG) material, their properties in the frequency-doubling process are systematically demonstrated and summarized, such as polarization dependence, symmetry point group, angle sensitivity, etc. The glass behaves more like uniaxial crystal. Their poling studied well, including time ultra-violet irradiation effects. results prove that second-order nonlinearity can be kept medium. In...

We present experimental results on kilojoule ultraviolet laser output with 1% spectral broadening. Through stimulated rotational Raman scattering (SRRS) signal injection, we achieve effective broadening in short-range propagation, good retention of the original near-field distribution and time waveform. Theoretical calculations show that 2% bandwidth can be achieved by injecting 20 kW/cm2 light at 2.2 GW/cm2 flux pump laser. In addition, high-frequency modulation near field effectively...
Optical poling and frequency doubling effect is one of the effective manners to induce second order nonlinearity realize in glass materials. The classical model believes that an internal electric field built when it's exposed by fundamental frequency-doubled light at same time, appears as a result orientation poles. process quasi phase matched. In this letter, physical optical deeply discussed detail. magnitude direction field, nonlinear coefficient its components, strength doubled output...
Kilo-joule Laser System (KLS) is constructed as a X-ray backlighting resource, to provide for performing diagnostic experiments. As crucial component of KLS, terminal system has such function frequency conversion, color separation, laser transport, beam focusing, target alignment and debris shielding, enabling focal spot energy(2ω) 500J in 1ns pulse, with accuracy ≤±25 μm.
