The dual-type qubit scheme is an emerging method to suppress crosstalk errors in scalable trapped-ion quantum computation and quantum networks. Here we report a hardware-economic way to control dual-type ${}^{171}\mathrm{Yb}^{+}$ qubits using a single $355\text{-nm}$ mode-locked pulsed laser. Utilizing its broad frequency comb structure, we drive the Raman transitions of both qubit types encoded in the $S_{1/2}$ and the $F_{7/2}$ hyperfine levels, and probe their carrier transitions and the motional sidebands. We further demonstrate a direct entangling gate between the two qubit types. Our work can simplify the manipulation of the ${}^{171}\mathrm{Yb}^{+}$ qubits both at the hardware and the software level.
