Recent development of intense terahertz (THz) pulses has enabled electric-field-driven ultrafast control of fundamental excitations such as molecular vibrations, superconductivity, and charge density waves, etc. Broadband mid-infrared (MIR) pulses can be used to understand these phenomena in time domain with resonance energy in the MIR frequency region. In this study, we developed a new optical system that near-infrared (NIR) and subcycle MIR and THz pulses were combined coaxially with retaining their broad bandwidth.
