Abstract

We propose an alternative excitation scheme based on paired-$\pi$-pulse input for laser cooling of solids in the superradiance regime. The dynamics of the activated atoms being pumped is analyzed, and used to deduce the temperature-dependent cooling power. Compared with the continuous-wave plus pulse pumping scheme, our scheme works better for laser cooling of solids via superradiance, and can improve the cooling power by 4 and 50 times at room and cryogenic temperatures, respectively.
