Lasing properties of buckled CdS NRs.
(a) The lasing spectra measured at flat part (w/o strain), valley part (compressive strain) and crest part (tensile strain) of CdS NRs under the same laser excitation power. Two lasing modes with very little energy shift under different strains are observed. (b) Only one lasing mode is observable at gain regime measured on a buckled CdS NR with narrow width (shorter cavity length). (c) The intensity of lasing modes (I and II) as a function of excitation power, which shows an almost the same lasing threshold.
