A supercontinuum source is a device that generates an extremely broad spectrum of light. We have built a packaged pulsed supercontinuum source. The source is used in our lab for characterization of optical filters. The source can be used for a wide range of application.
We use standard telecom fibers for supercontinuum generation. It allows for cost-effective and readily available components, which can be used to construct high-power, high-efficiency supercontinuum sources.
The unique properties of the supercontinuum source, including its broad spectral range, high brightness, and coherence, make it a valuable tool in many areas of science and technology. A nanosecond supercontinuum source is a type of supercontinuum source that generates a broad spectrum of light with nanosecond pulse duration. This is achieved by using high-energy nanosecond pulses from a laser to excite a nonlinear medium, which then generates a highly nonlinear response and produces a broad spectrum of light. high-brightness white-light spectrum covering the complete window of transparency of silica fiber in the infrared.

Near infrared (NIR) supercontinuum sources have a wide range of industrial applications, including:
Medical diagnostics: NIR supercontinuum sources can be used in medical diagnostics for non-invasive monitoring of tissue oxygenation, blood glucose levels, and blood flow. This technology can be used for early detection of diseases like cancer and cardiovascular diseases.
Material analysis: NIR spectroscopy is used for analysis of materials in various industries like food, agriculture, pharmaceuticals, and petrochemicals. NIR supercontinuum sources provide higher spectral resolution and faster measurement times than traditional light sources.
