A novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions has been constructed by Yao Fu and colleagues. The device can remotely probe chemical species in real time with high temporal resolution while monitoring the populations in their respective rovibronic levels in the frequency domain with sufficiently high spectral resolution.
