We demonstrate resonant excitation of quantum emitters in gallium nitride (GaN). The emitters are stable under non-resonant excitation and exhibit nearly Fourier-transform-limited lines of $\sim 250\mathrm{MHz}$ under coherent excitation, the narrowest reported to date for GaN.

氮化镓中量子发射体的共振激发

我们展示了氮化镓（GaN）中量子发射器的共振激发。发射器在非谐振激发下稳定，并表现出几乎傅立叶变换的限制线。$〜250\mathrm{兆赫}$ 在相干激发下，这是迄今为止报道的最窄的GaN。
