Dynamics of the emission spectrum of a neodymium-glass traveling-wave sweep laser

Time scans of the spectra of the radiation emitted from a neodymium-glass traveling-wave sweep laser revealed periodic stabilization of the emission frequency in the course of tuning of the dispersive laser resonator. This effect was attributed to an increase in the density of a "seed" field at the emission frequency resulting from narrowing of the spectrum in the traveling-wave regime.
