Fiber bundle technology improves the power and brightness of blue semiconductor laser Beam shaping using the same or close wavelength of the laser unit is the basis of multiple laser beam combination of different wavelengths. Among them, spatial beam bonding is to stack multiple laser beams in space to increase power, but may cause the beam quality to decrease. By using the linear polarization characteristic of semiconductor laser, the power of two beams whose vibration direction is perpendicular to each other can be increased by nearly twice, while the beam quality remains unchanged. Fiber bundler is a fiber device prepared on the basis of Taper Fused Fiber Bundle (TFB). It is to strip a bundle of optical fiber coating layer, and then arranged together in a certain way, heated at high temperature to melt it, while stretching the optical fiber bundle in the opposite direction, the optical fiber heating area melts into a fused cone optical fiber bundle. After cutting off the cone waist, fuse the cone output end with an output fiber. Fiber bunching technology can combine multiple individual fiber bundles into a large-diameter bundle, thus achieving higher optical power transmission. Figure 1 is the schematic diagram of blue laser fiber technology. The spectral beam combination technique utilizes a single chip dispersing element to simultaneously combine multiple laser beams with wavelength intervals as low as 0.1 nm. Multiple laser beams of different wavelengths are incident on the dispersive element at different angles, overlap at the element, and then diffract and output in the same direction under the action of dispersion, so that the combined laser beam overlaps each other in the near field and far field, the power is equal to the sum of the unit beams, and the beam quality is consistent. #Optical #photonics #semiconductor #Optics #opticalcenter #SiliconPhotonics #photodetectors #optomechanics #laser #Quantum Read more: https://lnkd.in/eaf5SA8j

Soft/hard differentiation of surface features at the nanoscale! I've been working on #biomaterials surfaces recently with the #afm and got nice information from phase imaging. One of the unique features of AFM is that it can give you nano-mechanical information about a surface, the easiest being the phase image. You get an immediate idea of what's on your surface and it's particularly useful for co-polymers of different stiffness. https://lnkd.in/ei8erwjq

Thrilled to share that our latest article has been published today in Science! https://lnkd.in/ggX_ezcb By carrying out scanning photovoltage microscopy, Hall, and Hanle measurements on 2D Ruddlesden-Popper perovskite (RPP) single crystals, we demonstrated highly efficient, electrically driven charge-to-spin conversion in enantiopure RPP crystals (⟨n⟩ = 4) at room temperature. We extracted parameters such as the spin Hall angle (θ_sh) and spin lifetime. We compared the performance with the racemic version of 2D RPP, as well as 2D RPPs of lower dimensionalities, and found that ⟨n⟩ = 4 chiral RPP single crystals show the highest charge-to-spin conversion efficiency of ~ 5%. As proof of the chirality-dependent spin Hall angle, we also demonstrated that θ_sh has opposite signs for the S and R enantiomers. This is a hallmark of chirality transfer from the organic to inorganic sublattices and a chirality-induced change in spin-orbit texture. Moreover, we identified that the orthogonality constraint between charge current, spin current, and spin polarization is lifted in such chiral hybrid perovskites. In addition to the conventional spin Hall conductivity (SHC) component observing the orthogonality relationship, an unconventional component where the spin current is collinear with the spin polarization is also observed. The collinear SHC component can be exploited for field-free magnetic switching through the spin-orbit torque switching mechanism. By exploring the intricate interplay between crystal chirality, spin-orbit coupling, and spin transport in hybrid perovskites, we can uncover new ways to manipulate and control spins. #perovskites #spintronics #spinorbitronics

Tuesday publication update! 📖 This newest publication in #SmallMethods from Raymond Unocic and Matthew Boebinger looks at the formation of 2D materials under an electron beam. Traditional methods like plasma etching and direct irradiation are effective are not extremely precise. This is why the authors used Electron-Beam Simulator (E-BeamSim) to observe the atomic movements and interactions resulting from electron beam irradiation at high temperature with the #FusionAX. 🔬 The Electron-Beam Simulator (E-BeamSim) tracks atomic movements and interactions during electron beam irradiation, providing unparalleled detail. 🌡️The MXene Ti3C2Tx at room temperature showed random atomic displacements and titanium pileups at nanopore edges. At elevated temperatures, after removing surface functional groups and increasing atomic mobility, the process leads to layer-by-layer selective atomic removal. These findings mark a significant leap in defect engineering within functionalized MXene layers and other 2D materials.💡 Read the entire paper here: https://hubs.ly/Q02DpYYG0 #Protochips #FindYourBreakthrough #InSituMicroscopy #HeatingMicroscopy #InSituTEM
