Monitored control of the coating process allows optical components to be precisely matched to the requirements of imaging or purely analytic systems. In applications such as fluorescence microscopy, parameters such as edge steepness or optical blocking (optical density) are factors that decisively affect the quality of the generated signal.   #photonics #biophotonics #materion #balzers #optics #coatings #bpf #opticalpackage #imaging #hyperspectral #multispectral #sensing #mirrors #filters #linear #variable #beamsplitters #assemblies #lifescience #sensors #fluorescence #microscope #spectroscopy

Tuesday publication update! 📖 Have you ever wanted to see MXenes in the electron microscope in real time using electrochemstry? The authors from #NTU of this newest publication have looked at Ti3C2Tx MXene Film for High-Performance Actuators using the #PoseidonAX system! 📈The enhancement of tetrabutylammonium (TBA) in MXene catapults the in-plane actuation strain by a staggering 337%, amplifying mechanical robustness and stability in air and electrolyte environments. 💧TBA and Li ions co-inserting/deserting into/from MXene interlayer galleries and inter-edge gaps trigger substantial in-plane sliding of MXene sheets under polarizations. This resulted in an actuator with exceptional strength and modulus, generating substantial strain differences and remarkable blocking forces at just 1 V. 🦾Additionally, using a soft robotic tweezer the authors were able to seize objects effortlessly at 1 V and firmly holding them at 0 V. The ingenious sheet sliding mechanism, akin to the filament sliding theory in skeletal muscles, opens doors for future high-performance actuators with diverse nanomaterials.

Focusing ultra-intense lasers to a single wavelength

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

Introduction to vertical cavity surface emitting semiconductor laser (VCSEL) Vertical external cavity surface-emitting lasers were developed in the mid-1990s to overcome a key problem that has plagued the development of traditional semiconductor lasers: how to produce high-power laser outputs with high beam quality in fundamental transverse mode. Vertical external cavity surface-emitting lasers (Vecsels), also known as semiconductor disc lasers (SDL), are a relatively new member of the laser family. It can design the emission wavelength by changing the material composition and thickness of the quantum well in the semiconductor gain medium, and combined with intracavity frequency doubling can cover a wide wavelength range from ultraviolet to far infrared, achieving high power output while maintaining a low divergence Angle circular symmetric laser beam. The laser resonator is composed of the bottom DBR structure of the gain chip and the external output coupling mirror. This unique external resonator structure allows optical elements to be inserted into the cavity for operations such as frequency doubling, frequency difference, and mode-locking, making VECSEL an ideal laser source for applications ranging from biophotonics, spectroscopy, laser medicine, and laser projection. The resonator of the VC-surface emitting semiconductor laser is perpendicular to the plane where the active region is located, and its output light is perpendicular to the plane of the active region, as shown in the figure.VCSEL has unique advantages, such as small size, high frequency, good beam quality, large cavity surface damage threshold, and relatively simple production process. It shows excellent performance in the applications of laser display, optical communication and optical clock. #Optical #photonics #semiconductor #Optics #opticalcenter #SiliconPhotonics #photodetectors #optomechanics #laser #Quantum Read more: https://lnkd.in/gCk5hGPt
