| Popis: |
Laser cooling allows vibration-free cryocooling down to 100K and appears as a promising technology for future satellite missions. We evaluate the impact of a laser cooler onboard a microsatellite on size, weight and power at platform levels and compare it to a mechanical cryocooler. Practically we intend to use a cooling head attached to the focal plane holding the instruments based on state-of-the-art cooling crystals 10 %Yb:YLF inside an astigmatic absorption cell. It will be linked by a fiber to a second system that includes the opto-electronics and laser. We will present initial results on a fiber-coupled cooling head. |
