EMITTER

ORiS is developing a sophisticated space payload for high-power laser transmission, integrating an advanced laser source, optical chain, targeting system, and thermal control mechanisms. The payload features a fiber laser source selected for its excellent beam quality, high efficiency, and compact size, which are essential for long-distance power transmission. To manage the laser beam effectively as it travels through space, the optical chain employs a combination of lenses and mirrors. This system is designed to maintain beam focus and power density, which are critical for ensuring reliable power transfer.

 The targeting system is a multi-layered solution for precision. It begins with the satellite’s Guidance, Navigation, and Control (GNC) system, which provides initial alignment. This is followed by a mechanical handling system that isolates vibrations and aligns a Fine Pointing System mounted on a movable support.

Thermal control is managed by active systems designed to handle the heat generated by the high-power laser. The system features a composite radiator equipped with a Shape Memory Alloy (SMA) that adjusts its configuration in response to temperature variations, thus enhancing heat dissipation. Among the various refrigerants being investigated, nanofluids are also being explored. 

Together, these integrated components ensure efficient and reliable high-power laser transmission in space, addressing the challenges of beam quality, targeting precision, and thermal management.

RECEIVER

ORiS is developing the receiver by considering both monochromatic photovoltaic cells, which are designed to convert light of a single wavelength into electrical energy, and commercially available triple-junction cells. These photovoltaic cells are mounted on a specially designed structure patented by ORiS, which minimizes geometric losses associated with the laser beam’s direction.
