We propose an alternative excitation scheme based on paired-π-pulses input for laser cooling of solids in superradiance regime. The dynamics of the activated atoms being pumped is analyzed, and used to deduce the temperature dependent cooling power. Compared with the continue-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. Moreover, the propagation effects of the input pulses are investigated to determine the proper length of the cooling sample.
