Hexagonal boron nitride (hBN), a wide-bandgap 2D material, is rapidly emerging as promising candidate for quantum optics experiments. In this work, we demonstrate, to the best of our knowledge, first signature Rabi oscillations, time-domain analogue Mollow triplet, from resonantly driven hBN emitter. Resonant photoluminescence excitation measurements reveal that emitter undergoes strong spectral diffusion with time scale 37±25 ms, resulting in 0.6 GHz broadened linewidth at weak limit. We further realize resonance fluorescence same using cross-polarized setup. The results shown here present an important step toward utilizing coherent optical control materials realization scalable information processing.
