Light sources providing a broad spectral range and well defined beam parameters are needed for numerous scientific experiments and technical applications. Lasers usually offer the advantageous beam properties but have a very small spectral width. To enhance the spectral bandwidth, high-harmonic or supercontinuum generations are commonly used. These require high-power lasers or highly nonlinear optical materials.
Powders containing SnS-based cluster molecules offer very strong nonlinear properties. They enable low-etendue, directional broadband supercontinua even when irradiated with a continuous-wave laser diode. Here, we present the nonlinear optical response of various powder compositions aiming to achieve a better understanding of the underlying processes responsible for the white light generation.
