Abstract

Random lasers use radiative gain and multiple scatterers in disordered media to generate light amplification. In this study, a random laser based on diamond nanoneedles that act as scatterers in combination with fluorescent dye molecules that serve as a gain medium has been demonstrated. Random lasers realized using diamond possess high spectral radiance with angle-free emission and thresholds of 0.16 mJ. The emission dependence on the pillar diameter and density is investigated, and optimum lasing conditions are measured for pillars with spacing and density of approximate to 336 +/- 40 nm and approximate to 2.9 x 10(10) cm(-2). Our results expand the application space of diamond as a material platform for practical, compact photonic devices, and sensing applications.
