Supercontinuum sources are used in various scientific experiments and technical applications. Such sources provide broad spectra with well-defined beam parameters. The most common method of generation such supercontinua is by using tapered or photonic-crystal fibers. In this approach, self-phase modulation of the propagating light in the fiber leads to the generation of the supercontinuum. To achieve the field strength required for this process one has to use pulsed pump sources.
Here, we present a powder compound, composed of organyl-protected [Sn4S6] cluster molecules, which shows extreme nonlinear properties. This material enables the generation of a supercontinuum by pumping with a medium-power, commercial, continuous-wave laser diode. The distinct geometry and frustrated mesoscopic order of the tinsulfide-based cluster molecules is responsible for the nonlinear response. By studying the nonlinear properties we are getting closer to characterize and understand the material system.
