AI Article Synopsis
- A green-emitting organic quasicrystal microcavity laser is demonstrated using a conjugated complex PVK: Ir(ppy) and is powered by optical pumping.
- The laser features a sandwich structure that includes a DBR, an organic gain membrane, and an output silver layer for efficient vertical light oscillation, along with an octagonal quasicrystal for in-plane light localization.
- Experimental results reveal single-mode lasing at a wavelength of 521 nm with a narrow bandwidth (0.8 nm) and a low lasing threshold of 0.181 μJ/cm.
Article Abstract
Based on the conjugated complex PVK: Ir(ppy), a green-emitting organic quasicrystal microcavity laser is demonstrated driven by optical pumping. The organic laser adopts a sandwich structure of DBR/organic gain membrane/output Ag-layer for the vertical oscillation and an octagonal quasi-crystal for in-plane light localization. The experimental results show that the single-mode lasing action is observed at 521 nm with an FWHM of 0.8 nm. The threshold of lasing is lowered to 0.181 μJ/cm.
