When certain media are irradiated with intense laser light, under specific conditions, the scattered light exhibits the properties of stimulated emission and is coherent radiation. This phenomenon is known as Stimulated Raman Scattering (SRS). Barium nitrate crystals are among the best solid-state materials exhibiting the Stimulated Raman Scattering effect, capable of converting the frequency of the pump laser into multiple different spectral ranges.
