Spectral Line Formation [PDF]

open access: possible, 2012
This chapter gives a review of spectral line formation processes, starting with the main equations valid in thermodynamic equilibrium. The Einstein coefficients and the main spectral line profile functions are discussed.

Spectral line-by-line pulse shaping [PDF]

open access: possibleOptics Letters, 2005
We experimentally demonstrate pulse-shaping experiments in which the individual spectral lines that are present in the output of a mode-locked laser (8.5 GHz mode spacing, centered at 1542 nm) are resolved. The shaped pulses overlap in time, and this leads to a new way to observe fluctuations of the comb-offset frequency in the time domain.

Detection and Estimation of a Spectral Line in MIMO Systems

Asilomar Conference on Signals, Systems and Computers, 2020
We consider the problem of detecting and estimating the dispersion parameters (delay, direction of departure, direction of arrival) of a single specular multipath component in the presence of a dense multipath component and thermal RF noise from ...

Spectral Lines for Refractometry

Journal of the Optical Society of America, 1963
This note contains proposals made at the 6th meeting of the International Commission for Optics in Munich, 1962, for a series of wavelengths for refractometry extending from 2139 + to 23254 +, together with a statement of the procedure then agreed.

Spectral line shapes. II

Molecular Physics, 1985
A spectral line shape function theory is extended for gaseous systems where reactive collisions can occur. The theory of subdynamics and the Fock-Tani representation are used in order to attempt this goal. The dependence of the spectral shape on the pressure and the reactive transition probability is clarified. Finally^a discussion concerning the above

The Spectral Line

Bulletin (Society for Applied Spectroscopy), 1951
Harold Hughes took a bit of his time during his vacation hideway at Lake Memphramagog, Vt., to report that among the members and friends of SAS who attended the summer meetings of ASTM at Atlantic City were the following: Charles Guettel and his family, E. J. Dunn, Jr., paul Lighty, B. F. Scribner, H. K. Hughes, E. K. Jaycox, C. Jedlicka, R.
