Abstract

This study is the first to investigate novel cone lasers and the tunabilities of their lasing feature and performance based on dye-doped cholesteric liquid crystal (DDCLC) films with various LC birefringences (Δn). A unique conically-symmetric lasing ring with a low energy threshold occurs at a specific nonzero oblique angle (θring). The low energy threshold is comparable to those for common lasing signals occurring simultaneously at the short- and long-wavelength edges (SWE and LWE) of the CLC reflection band (CLCRB) for 0°. The lasing ring is induced by the enhancement in the density of photonic state for the fluorescence with a wavelength of λring based on an edge-overlapping effect, in which λring is just located at an edge-overlapping spectral position of the SWE of the CLCRB for 0° and the LWE of the CLCRB for θring. The lasing feature (i.e., the lasing wavelengths of the three lasing signals and the emitted angle of the lasing ring) are tuned by varying Δn. The simulated relationship of an oblique angle with Δn, in which the SWE of the CLCRB for that oblique angle just overlaps the LWE of the CLCRB for 0°, can be obtained by calculating the dispersion relation of a planar CLC structure with various values of Δn based on Berreman’s 4 × 4 matrix approach. The result of the calculation is highly consistent with the experimental data for the dependence of θring on Δn. Furthermore, the dependence of lasing performance (energy threshold and relative slope efficiency) on Δn for the three lasing signals is also measured, which findings can be used to qualitatively identify positive interaction or competition among the three lasing signals.

(a.1)–(a.4) [(a.5)–(a.8)] Obtained lasing patterns and (b.1)–(b.4) [(b.5)–(b.8)] the measured lasing and transmission spectra at E = 8 μJ/pulse; (c.1)–(c.4) [(b.5)–(b.8)] the variations in the lasing intensity with the incident pumped energy for lasing signals at the LWE and SWE for 0° and at the LWE for 29°, 34.6°, 43.6°, and 50° based on DDCLC cells 1–4 (5–8) with Δn1–Δn4, respectively.

(a) Variation in the edge-overlapping wavelength of the lasing ring and the lasing at the SWE for 0° [λring = λlas,SWE(0°)] with Δn based on cells 1–4 (represented by blue dots), and that in the wavelength of the lasing at the LWE for 0° [λlas,LWE(0°)] with Δn based on cells 5–8 (represented by red dots). (b) Variation in the emitted oblique angle for the lasing ring (θring) with Δn in the experiment (represented by red diamonds), and that in the simulated oblique angle (θoverlap) in which the LWE of the corresponding CLCRB overlaps with the SWE of the CLCRB for 0° with Δn in the simulation (represented by open diamonds) based on cells 1–4 or 5–8.

Variations in (a) the energy threshold and (b) the relative slope efficiency with Δn for the lasing signals with λlas,LWE(0°), λlas,SWE(0°), and λring (represented by diamond, triangular, and circular dots, respectively) based on cells 1–4. The blue curve in (a) and (b) represents the fluorescence emission spectrum of the laser dye.
