Abstract

Wu et al.1 demonstrated a two-dimensional (2D) material-based laser that required only 1 W cm−2 of pump power to reach the threshold limit. This value is low enough to be optically driven by a regular household light bulb! Reducing the power level for the onset of lasing action is a desirable goal in laser science. A series of design choices led to this breakthrough: (1) the 2D gain material exhibited high conversion efficiencies; and (2) the laser cavity—a photonic crystal cavity (PCC)—had a high quality factor (Figure 1).
