Abstract

Laser coolers are an innovative class of coolers capable of reaching cryogenics temperatures in a miniaturized, contact-less and entirely vibration free way. Hence they are considered as a potential breakthrough technology for space cryogenics, especially in the field of earth-observation missions. We have developed and successfully operated a fiber-coupled laser cooling prototype. We will present a possible architecture for the laser source that could meet space requirements and review possible alternative solutions like intra-cavity cooling and using Ho-doped fluoride crystals.
