VO2-based Thin-Film Smart Radiator Device for improved Passive Thermal Control of Space Systems

The VO2-based Thin-Film Smart Radiator Device (SRD) improves passive thermal control for spacecraft by adjusting its emissivity based on external temperature, helping to regulate internal temperatures without excessive power use. Using a thin film of tungsten-doped VO2, the SRD shifts between a low-emissivity, heat-conserving state and a high-emissivity, heat-releasing state, depending on the thermal environment. This technology reduces the need for heaters, extending satellite lifespan and mission efficiency, with successful ground tests meeting European Space Agency (ESA) standards.

Pulsed 695-nm Sub-Nanosecond Source Based on Backward-Pumped Raman Fiber Amplifier

Compact source of sub-nanosecond second-harmonic 695-nm pulses at repetition rates of 35 to 80 MHz is presented. Source is based on a backward-pumped polarization-maintaining Raman phosphosilicate fiber amplifier pumped by an 1173-nm Raman fiber laser.

A remotely-pumped 130-W 1178-nm single-frequency linearly-polarized Raman fiber amplifier

Remotely pumped by a single-mode, polarization-maintaining (PM) 1120-nm fiber laser, a single-frequency linearly-polarized 1178-nm Raman fiber amplifier (RFA) has been developed with a maximum continuous-wave (CW) output power of 130-W. This remotely-pumped high-power RFA system features the same modular, compact and ruggedized design as the proven SodiumStar 20/2 and provides the potential for a guide star laser with a 589-nm output power approaching 100-W, assuming a 10 to15% D2b sideband content and a typical overall conversion efficiency of a resonant second harmonic generator of ~ 70%

We present a fully-integrated, two-color fiber laser system delivering sub-nanosecond pulses at 589 nm and 655 nm. Using a backward-pumped Raman fiber amplifier and fiber-coupled SHG modules, the system achieves high repetition rates (40–100 MHz) and up to 3 W output power per wavelength, while maintaining excellent beam quality (M²<1.05).

A mature 100-W 1178-nm single-frequency linearly polarized Raman fiber amplifier for laser guide star assisted optical ground station adaptive optics systems

Next-generation satellite constellations use optical inter-satellite links for better capacity, but RF feeder links to ground stations remain a bottleneck. To transition to all-optical links, challenges like atmospheric turbulence need to be addressed, with Laser Guide Star (LGS) adaptive optics as a key solution. A new 100-W Raman fiber amplifier (RFA) has been developed, offering high power and reliability for LGS systems. This RFA, which efficiently suppresses stimulated Brillouin scattering (SBS), has demonstrated robustness in long-term testing. Future optimization could push its power output beyond the current 100-W level, enabling more powerful guide star lasers for optical ground stations.

The impact of signaling pathways on the desmosome ultrastructure in pemphigus

In this study on pemphigus vulgaris, researchers investigated how various disease-related signaling pathways affect desmosome structure and integrity in the epidermis. To analyze protein organization at high resolution, fluorophores were selectively depleted using MPBC's 775 nm pulsed fiber laser.

Rapid lightsheet fluorescence imaging of whole Drosophila brains at nanoscale resolution by potassium acrylate-based expansion microscopy

In this study, researchers applied expansion microscopy (ExM) to mechanically stabilized Drosophila brains using potassium (poly)acrylate-based hydrogels, enabling over 40x resolution enhancement of fluorescent proteins preserved with glutaraldehyde fixation. To capture detailed images across the large brain volume, they employed an axicon-based Bessel lightsheet microscope for gentle, multi-color excitation and high-speed optical sectioning. This approach allowed for the visualization of fine neuronal structures, such as Tm5a neurites, L3 lamina neurons, and presynaptic mitochondria, at a resolution comparable to electron microscopy. For multi-color fluorescence imaging, the optical setup integrated multiple excitation sources, including 488 nm, 560 nm, and 642 nm lasers from MPBC, supporting the high-resolution mapping of the expanded nervous tissue.
