Abstract
| - Abstract. A study is presented of the total differential Raman cross section for CO2, O2, CO, CH4, H2O and H2 relative to that of N2. The scattered radiation was collected perpendicularly to the excitation beam from a 337.1 nm nitrogen laser of 50 kW peak power. The short pulse with a duration of 2.5 ns was conveniently handled by a sampling oscilloscope. The sampling technique permits a smoothing process to be performed at the output of the sampling oscilloscope, which does not affect the time resolution, in order to improve the signal-to-noise ratio of the records of Raman spectra.
