Abstract
Raman scattering from metastable excited nitrogen molecules N2(A3Σu+) created by an impulse discharge in nitrogen at atmospheric pressure was detected. A pulsed Nd:YAG laser of wavelength 266 nm was used as the light source, and Raman scattering from N2(A3Σu+) at wavelength 277 nm was detected using an interference filter and photomultiplier tube. The filter had sufficient rejection of Rayleigh scattering of laser light at wavelength 266 nm and Raman scattering from ground state nitrogen molecules N2(X1Σg+) at wavelength 284 nm. The temporal variation of the signal intensity of Raman scattering from N2(A3Σu+) was measured by transmitting the laser at different time delays relative to sparkover. Results showed that the signal intensity decayed with a time constant of about 200 μs.
