(Color online) Schematic setup of lasing measurement.
SEM image shows the surface morphology of a PDLC with nanoscale LC droplets.
(Color online) Emission spectra with various pumping energies of (a) 20, (b) 25, (c) 28, (d) 35, and (e) /pulse, respectively. The insets I and II are an emission photograph of the dye-doped PDLC excited at /pulse and a schematic diagram showing the formation of a closed loop path of light through recurrent scattering in a PDLC, respectively.
(Color online) The output intensity and FWHM of the ASE spectra from DCM-doped PDLC film as functions of the laser pumping energy.
(Color online) (a) TE and (b) TM polarized emission spectra for the DCM-doped PDLC film.
