    • Nanosecond colloidal quantum dot lasers for sensing 

      Guilhabert, B.; Foucher, C.; Haughey, A M.; Mutlugun, E.; Gao, Y.; Herrnsdorf, J.; Sun, H. D.; Demir, Hilmi Volkan; Dawson, M. D.; Laurand, N. (Optical Society of America, 2014)
      Low-threshold, gain switched colloidal quantum dot (CQD) distributed-feedback lasers operating in the nanosecond regime are reported and proposed for sensing applications for the first time to the authors' knowledge. The ...
    • Near resonant third-order optical nonlinearities of colloidal InP/ZnS quantum dots 

      Wang, Y.; Yang, X.; He, T. C.; Gao, Y.; Demir, Hilmi Volkan; Sun, X. W.; Sun, H. D. (AIP Publishing, 2013)
      We have investigated the third-order optical nonlinearities of high-quality colloidal InP/ZnS core-shell quantum dots (QDs) using Z-scan technique with femtosecond pulses. The two-photon absorption cross-sections as high ...
    • Stimulated emission and lasing from CdSe/CdS/ZnS core-multi-shell quantum dots by simultaneous three-photon absorption 

      Wang Y.; Ta, V. D.; Gao, Y.; He, T. C.; Chen R.; Mutlugun, E.; Demir, Hilmi Volkan; Sun, H. D. (Wiley - V C H Verlag GmbH, 2014)
      Three-photon pumped stimulated emission and coherent random lasing from colloidal CdSe/CdS/ZnS core-multishell quantum dots are achieved for the first time. These results can offer new possibilities in biology and photonics, ...
