Study Notes
Spectral Line Characteristics
- The width of a spectral line at half of its maximum intensity is referred to as the Full Width at Half Maximum (FWHM).
Einstein Coefficients and Absorption
- The equation that links the total area under the curve, Einstein coefficients, and population of states causing the absorption around the resonance frequency is the Einstein Equation.
Line Broadening
- In Homogeneous Line Broadening, all two-level atomic systems have the same lineshape function and atomic resonance frequency.
Spectral Line Width
- The term commonly used to refer to the width of a spectral line, despite not meaning 0.5 width, is the natural linewidth.
Spontaneous Emission Radiation
- The plot that describes the spontaneous emission radiation intensity as a function of frequency (or wavelength) for a specific lasing transition is the Spectral Lineshape.
