A research team of the National Institutes of Natural Sciences, National Institute for Fusion Science and Akita Prefectural University have successfully demonstrated a broadband mid-infrared (MIR) source with a simple configuration.
This light source generates highly-stable broadband MIR beam at 2.5-3.7 μm wavelength range maintaining the brightness owing to its high-beam quality. Such a broadband MIR source facilitates a simplified environmental monitoring system by constructing a MIR fiber-optic sensor, which has the potential for industrial and medical applications.
In the MIR wavelength region, there are many strong absorption lines of molecules due to the change of their rotational and vibrational states. Therefore, by using MIR sources, we have promising opportunities to develop sensitive remote monitoring systems of practical use.
