Methane detection is demonstrated for laser-based and thermal illumination. Applicability towards further laser-based detection methods is considered.ensignal upconversioninfrared radiationmethane detectionLaser-Based Detectiongas spectroscopy621MWIR upconversion detection for infrared gas spectroscopyconference paper
