Laser optogalvanic spectroscopy of neon at 659.9 nm in a discharge plasma and nonlinear least-squares fitting of associated waveforms Original Research Article

Laser optogalvanic spectroscopy of neon has been studied in the discharge environment of a hollow cathode discharge lamp. We illustrate the fitting of the time-resolved optogalvanic waveforms by focusing on the 1s2–2p2 transition of neon at 659.9 nm and employ a nonlinear least-squares Monte Carlo approach to determine the pertinent amplitude coefficients, decay rates and the instrumental time constant.
