High-Resolution Time-Stretch Infrared Spectroscopy with Frequency Down-Conversion of Near-Infrared Lasers
We present a study on time-stretch infrared spectroscopy around 3.4 μm, utilizing frequency down-conversion of near-infrared lasers. Our measurement of methane gas achieved a rate of 50 MSpectra/s, with a spectral resolution of 0.088 cm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup>.
