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.
