Abstract We use femtosecond time-resolved optical reflectivity to study the photoexcited quasiparticle (QP) dynamics in the iron-based 112 type superconducting (SC) samples Ca$_{0.82}$La$_{0.18}$Fe$_{1-x}$Ni$_{x}$As$_{2}$, with $x = 0$ and 0.024. In the parent sample, a fast and a slow relaxation emerge at temperatures below the magnetic-structure (MS) transition $T_{\rm ms} \approx 50$ K and the SC transition $T_{\rm c} \approx 33$ K, respectively. The latter obviously corresponds to an SC QP dynamics, which is further confirmed in the $x = 0.024$ sample with $T_{\rm c} \approx 25$ K. The former suggests that a partial of photoexcited QP relaxation through a pesudogap (PG) channel, which is absent in the doped $x = 0.024$ sample without the MS transition.
