TLDR
Wu et al. as discussed by the authors demonstrated a two-dimensional (2D) material-based laser that required only 1 W cm−2 of pump power to reach the threshold limit, which is low enough to be optically driven by a regular household light bulb.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).read more

TL;DR: A new lasing strategy is reported: an atomically thin crystalline semiconductor—that is, a tungsten diselenide monolayer—is non-destructively and deterministically introduced as a gain medium at the surface of a pre-fabricated PCC, allowing an optical pumping threshold as low as 27 nanowatts at 130 kelvin similar to the value achieved in quantum-dot PCC lasers.

TL;DR: It is argued that to accurately evaluate the Purcell effect, both the passive cavity boundary and the collective effect of all emitters must be included as part of the mode environment.
