Black phosphorus has attracted attention as a layered material exhibiting mid-infrared emission. However, investigating its emission dynamics has remained technically challenging. In this study, we successfully measured the temporal evolution of emission from black phosphorus using a mid-infrared emission detection technique based on wavelength upconversion. Furthermore, we observed picoseconds stimulated emission under high-intensity optical excitation.
