MPBC has developed a functional prototype of a high pulse energy laser, featuring a polarization-maintaining Erbium-Ytterbium doped fiber amplifier with an average output power exceeding 20 W. Operating within a wavelength range of 1545–1565 nm, this compact unit includes a collimated pigtailed output, tunable pulse repetition rates from 0.05 to 50 MHz, and adjustable pulse durations between 2–100 ns. The system achieves peak power levels up to 4 kW and pulse energies of up to 80 µJ, with a linewidth (1/e²) of ≤50 pm.
Designed for versatility, this laser system is ideal for applications such as photo-acoustic imaging, deep space communications, and scientific research. To address optical design challenges in amplifiers for deep space communications, MPBC is focused on achieving high pulse peak power and energy. The system is being designed to meet the CCSDS 141x0b1 standard and investigates the potential of hollow-core anti-resonant fibers for efficient delivery of high-peak power pulses.

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.
