Highly efficient amplified stimulated emission from CdSe-CdS-ZnS quantum dot doped waveguides with two-photon infrared optical pumping
Tunable, room-temperature, amplified stimulated emission (ASE) is generated in quantum dot (QD)-doped nanocomposites through two-photon optical pumping in the near infrared (see figure). Utilizing a zirconia host matrix temporal stability comparable to that of ASE generated through optical pumping in the 1-photon excitation region is demonstrated.
