Operation of a fiber-coupled laser cooled down to cryogenic temperatures

Operation of a fiber-coupled laser cooled down to cryogenic temperatures

We report on the optical cooling of a 7.5%Yb:LiYF4 crystal down to 125 K in a multi-pass Herriott absorption cell, coupled via a single mode polarization maintaining optical fiber to the laser source. This configuration, never exploited before, is more practical for potential applications, in partic...
