| dc.description | We present new results of a laser phenomenon that gives rise to a narrow green emission mode in a random photonic-crystal cavity based on an Er-doped glass–air gap–polymer with a 976 nm diode laser pump. Lasing occurs at 537 nm, which does not respond to the resonant radiative transition <sup>2</sup>H<sub>11/2</sub>→<sup>4</sup>I<sub>15/2</sub>; <sup>4</sup>S<sub>3/2</sub>→<sup>4</sup>I<sub>15/2</sub> in Erbium ions. This effect can be seen as photon–atom coupling in the context of the interaction between a single atom and/or a few atoms and resonant optical media, such as cavities or photonic crystals. Experimental results show that the random lasing mode directly originates from the coupled photon–atom mode inside the random cavity. The measured Q-factor is of 2100–2800 for a random cavity with an air gap of 600–1700 nm between Er-doped glass fiber and a coated polymer layer. |
