Multimodal nonlinear optical (NLO) imaging is a microscopy approach used in a variety of biomedical applications. It harnesses and integrates the unique capabilities of nonlinear processes such as multiphoton fluorescence, second- and third-harmonic generation (SHG and THG), and coherent Raman scattering (CRS) and combines them seamlessly into a single, unified microscopy platform.

Thin-film silicon (Si) photovoltaics are a combination of amorphous and microcrystalline Si; monitoring the proportions via Raman spectroscopy and high-performance optical filters allows the cells to be optimized during manufacture. Learn More
594-nm laser excitation can enhance our ability to analyze cells by flow cytometry. This laser wavelength fills a significant excitation gap between the now common 561-nm line and the red laser sources. Adding this wavelength to the excitation repertoire enables excitation of virtually any visible fluorescent probe for cytometric analysis. Learn More
With carefully controlled absorption and scattering losses, high-reflectivity, low-loss dielectric mirrors enable demanding applications such as gravitational-wave detection and cavity ring-down spectroscopy. Learn More
